DIY Bench Cushions: A Step-by-Step Guide to Sewing Your Own Comfortable Seating

Creating custom bench cushions is a fantastic way to add comfort, style, and personality to your indoor or outdoor spaces. Whether you have a built-in bench, a repurposed church pew, or a simple garden bench, a well-made cushion can transform it into a cozy and inviting spot. Sewing your own bench cushions allows you to choose the perfect fabric, size, and thickness to match your décor and needs. This comprehensive guide will walk you through every step of the process, from measuring your bench to adding the final touches. Let’s get started!

## Materials You’ll Need

Before you begin, gather all the necessary materials. This will make the process smoother and prevent interruptions.

* **Fabric:** Choose a durable fabric that suits your intended use. For outdoor cushions, opt for weather-resistant options like outdoor canvas, Sunbrella, or marine-grade vinyl. For indoor cushions, consider upholstery fabric, cotton duck, linen blends, or even repurposed materials like old blankets or curtains. The amount of fabric you need will depend on the size of your bench and the desired cushion thickness. Be sure to buy extra fabric for mistakes and adjustments – at least an extra ½ yard.
* **Foam:** High-density foam is ideal for bench cushions as it provides good support and holds its shape well. You can purchase foam specifically designed for upholstery or use a firm foam mattress topper. Consider the thickness of the foam based on the desired level of comfort. 2-4 inches is standard, but you might want thicker foam for more plush seating. Check local upholstery shops or online retailers for the best selection.
* **Batting (Optional):** Adding a layer of batting around the foam core can create a softer, more rounded look. Polyester batting is a good choice as it is lightweight and dries quickly. Quilters batting is another option to add loft and a softer edge.
* **Measuring Tape:** Essential for accurately measuring your bench and calculating fabric requirements.
* **Scissors or Rotary Cutter and Mat:** For cutting fabric precisely.
* **Straight Pins:** To hold fabric pieces together before sewing.
* **Sewing Machine:** A reliable sewing machine is a must-have.
* **Thread:** Choose a strong thread that matches your fabric. For outdoor cushions, use UV-resistant thread to prevent fading and deterioration.
* **Zipper (Optional):** A zipper allows you to easily remove the cushion cover for washing or replacement. Choose a zipper that is slightly shorter than the length of one side of your cushion.
* **Buttons or Ties (Optional):** For adding decorative details or securing the cushion to the bench.
* **Pencil or Fabric Marker:** To mark cutting lines on the fabric.
* **Ruler or Yardstick:** To create straight lines when marking fabric.
* **Iron and Ironing Board:** To press fabric before and after sewing.

## Step-by-Step Instructions

Follow these detailed instructions to create your own beautiful and comfortable bench cushions.

### 1. Measure Your Bench

Accurate measurements are crucial for a well-fitting cushion. Measure the length, width, and desired thickness of your bench.

* **Length:** Measure the distance from one end of the bench to the other.
* **Width:** Measure the distance from the front to the back of the bench.
* **Thickness:** Decide how thick you want your cushion to be. This will determine the thickness of the foam you purchase. Adding extra inches on the fabric measurement will give a larger fill for the foam.

Write down all measurements clearly and double-check them to avoid errors.

### 2. Calculate Fabric Requirements

Determine how much fabric you need based on your bench measurements and desired cushion design.

* **Top and Bottom Pieces:** For a simple rectangular cushion, you’ll need two pieces of fabric: one for the top and one for the bottom. Each piece should be cut to the length and width of your bench, plus seam allowances. Add at least 1/2 inch seam allowance on all sides.

* **Example:** If your bench is 48 inches long and 18 inches wide, and you want a 1/2-inch seam allowance, cut two pieces of fabric that are 49 inches long and 19 inches wide.

* **Side Pieces (Optional):** If you want a thicker cushion with boxed edges, you’ll need to cut side pieces. The length of the side pieces should equal the perimeter of the top piece (2 x length + 2 x width), and the width should equal the desired thickness of your cushion plus seam allowances.

* **Example:** Using the same bench measurements as above, and wanting a 3-inch-thick cushion with a 1/2-inch seam allowance, the side piece should be (2 x 48 + 2 x 18) = 132 inches long and 3.5 inches wide.

* **Zipper Allowance (If Using):** If you’re adding a zipper, factor in an extra inch or two of fabric on the side where the zipper will be placed. This will allow for easier insertion and removal of the cushion.

* **Example:** If your zipper is going on the back of the cushion, add an extra 1 inch to the back piece. This makes it 20 inches.

* **Batting Requirements (If Using):** Batting should be cut slightly larger than the foam core to wrap around it completely. Add 2-3 inches to each dimension of the foam.

Draw a simple diagram of your cushion design and label all the measurements to help you visualize the cutting process.

### 3. Cut the Fabric

Lay your fabric on a flat surface and use a ruler or yardstick to measure and mark the cutting lines. Use a fabric marker or pencil to ensure accurate lines.

* **Cutting the Top and Bottom Pieces:** Cut out the top and bottom pieces according to your calculated measurements. Ensure the fabric is smooth and wrinkle-free before cutting.

* **Cutting the Side Pieces:** If you’re adding side pieces, cut them according to the calculated length and width. For long side pieces, you may need to join multiple fabric strips together. Use a sewing machine to stitch the strips together with a 1/2-inch seam allowance, and press the seams open.

* **Cutting the Batting:** Cut the batting to the appropriate size, ensuring it’s slightly larger than the foam core.

### 4. Prepare the Zipper (Optional)

If you’re using a zipper, now is the time to prepare it.

* **Attaching the Zipper to the Fabric:** Place the zipper face down along the edge of one of the fabric pieces (usually the back piece). Use pins to secure the zipper in place, ensuring the zipper teeth are aligned with the fabric edge. Use a zipper foot on your sewing machine to stitch the zipper to the fabric with a 1/2-inch seam allowance.

* **Repeat for the Other Side:** Repeat the process for the other side of the zipper, attaching it to the other fabric piece. Make sure the zipper is aligned correctly so that the fabric pieces meet evenly when the zipper is closed.

* **Test the Zipper:** Open and close the zipper to ensure it works smoothly. If there are any issues, adjust the stitching as needed.

### 5. Sew the Cushion Cover

Now it’s time to sew the cushion cover together.

* **Attaching the Side Pieces (If Using):** Pin the side pieces to the top piece, aligning the raw edges. Start at one corner and work your way around, easing the fabric as needed to create a smooth curve. Use a sewing machine to stitch the side pieces to the top piece with a 1/2-inch seam allowance. Clip the corners and any curved seam allowances to reduce bulk.

* **Attaching the Bottom Piece:** Pin the bottom piece to the side pieces, aligning the raw edges. Leave the zipper partly open. Use a sewing machine to stitch the bottom piece to the side pieces with a 1/2-inch seam allowance, leaving an opening for turning the cushion cover right-side out if you are not using a zipper. Backstitch at the beginning and end of each seam to secure the stitching.

* **Sewing Without Side Pieces:** If you’re not using side pieces, simply pin the top and bottom pieces together, right sides facing. Sew around three sides with a 1/2-inch seam allowance. Leave one side open for turning and inserting the foam. Backstitch at the beginning and end of each seam.

### 6. Turn the Cushion Cover Right-Side Out

Carefully turn the cushion cover right-side out through the opening you left (or through the zipper opening). Use a point turner or a dull pencil to push out the corners and create sharp edges. If you didn’t use a zipper, carefully hand stitch the opening with a hidden stitch.

### 7. Insert the Foam and Batting

Now it’s time to insert the foam core and batting (if using) into the cushion cover.

* **Wrapping the Foam with Batting:** Lay the batting on a flat surface and place the foam core in the center. Wrap the batting around the foam, securing it with pins or basting stitches. This will create a softer, more rounded look for the cushion.

* **Inserting the Foam into the Cover:** Carefully slide the foam core (wrapped in batting, if applicable) into the cushion cover through the opening. Ensure the foam is positioned correctly and fills the cover evenly. If you’re using a zipper, make sure the zipper is fully open to allow for easy insertion.

* **Close the Opening:** If you didn’t use a zipper, carefully hand stitch the opening with a hidden stitch. Make sure the stitching is strong and secure to prevent the cushion from coming apart.

* **Close the Zipper:** If you used a zipper, close it securely.

### 8. Add Finishing Touches (Optional)

Add any desired finishing touches to your bench cushions to customize their look.

* **Buttons:** Add decorative buttons to the top of the cushion for a tufted look. Use upholstery needles and strong thread to attach the buttons securely.

* **Ties:** Sew fabric ties to the corners of the cushion to secure it to the bench. Cut strips of fabric, fold them in half lengthwise, and stitch them together to create the ties. Attach the ties to the cushion corners with a sewing machine or by hand.

* **Piping:** Add piping to the edges of the cushion for a more polished look. Purchase pre-made piping or make your own using fabric and cording. Attach the piping to the cushion edges before sewing the top and bottom pieces together.

* **Topstitching:** Add topstitching around the edges of the cushion for a decorative touch and to reinforce the seams. Use a slightly longer stitch length and a contrasting thread color for added visual interest.

### 9. Test and Enjoy

Place your finished bench cushions on your bench and test them out. Make any necessary adjustments to ensure they are comfortable and fit well. Once you’re satisfied, sit back, relax, and enjoy your new custom-made seating!

## Tips for Success

* **Choose the Right Fabric:** Consider the intended use of your bench cushions when selecting fabric. For outdoor cushions, opt for weather-resistant fabrics that can withstand sun, rain, and mildew. For indoor cushions, choose fabrics that complement your décor and are durable enough to withstand everyday use.
* **Use High-Quality Foam:** Invest in high-density foam that provides good support and holds its shape well. Cheaper foam may flatten out quickly and lose its comfort.
* **Take Accurate Measurements:** Accurate measurements are essential for a well-fitting cushion. Double-check your measurements before cutting any fabric.
* **Use a Walking Foot:** If you’re sewing thick fabrics, consider using a walking foot on your sewing machine. A walking foot helps to feed multiple layers of fabric evenly, preventing them from shifting or puckering.
* **Press as You Sew:** Pressing your fabric before and after sewing each seam will help to create a professional-looking finish.
* **Use a Zipper Foot:** When sewing zippers, use a zipper foot on your sewing machine. A zipper foot allows you to sew close to the zipper teeth without damaging them.
* **Clip Curved Seam Allowances:** Clipping curved seam allowances will help to reduce bulk and create a smoother curve.
* **Take Your Time:** Sewing bench cushions can be a time-consuming project, so be patient and take your time. Rushing through the process can lead to mistakes and a less-than-perfect result.
* **Don’t Be Afraid to Experiment:** Don’t be afraid to experiment with different fabrics, designs, and embellishments. The possibilities are endless!

## Care and Maintenance

To keep your bench cushions looking their best, follow these care and maintenance tips:

* **Regular Cleaning:** Vacuum your bench cushions regularly to remove dust and debris. Spot clean any stains with a mild soap and water solution. For outdoor cushions, hose them down occasionally to remove dirt and grime.
* **Sun Protection:** Prolonged exposure to sunlight can cause fabrics to fade and deteriorate. If your bench cushions are located in a sunny area, consider using a fabric protectant spray or covering them when not in use.
* **Storage:** When not in use, store your bench cushions in a dry, protected area to prevent mildew and damage. Consider using a cushion storage bag or container.
* **Professional Cleaning:** For stubborn stains or deep cleaning, consider taking your bench cushions to a professional upholstery cleaner.
