By now you’ve probably seen the cozy little outdoor space that we created at our studio so we can soak up some good summertime vibes outdoors. Josh made amazing bench seating to give us a place to lounge, but it can be difficult to lounge properly on stiff wooden boards, so we decided to add some thick outdoor cushions to make our seating area more comfortable. Here’s what I did:
-canvas twill or outdoor fabric (I bought our stripe fabric at a local fabric store)
-outdoor cushion filling (like this)
-standard sewing machine
-zipper the width of your cushion
-fabric scissors and sewing pins
To figure out the fabric dimensions for the cushion panels, take the width and depth measurements and add 1″ to both numbers to allow for a 1/2″ seam allowance all around. These measurements are for the top and bottom panels of the cushion. To determine the side panel length, add the original measurements (the numbers before the additional inches for seam allowance) of all four sides of the large panel together. Add 1″ onto that big number to allow for a 1/2″ seam allowance. The height of your super-long side panel is the height of the cushion filling with 1″ added for a 1/2″ seam allowance.
Take these dimensions and cut your top and bottom panel and your long side panel accordingly.
Use fabric scissors to round the edge of your fabric corners on your two larger panels. To connect your long side panel strip and make one big continuous loop around the edge of your cushion, fold the panel in half (with the right sides facing each other), and sew 1/2″ from the edge to connect the ends. Line up the edges of your side panel loop of fabric with the edge of the top panel (with the right sides together), and pin the edge in place.
Before you sew all the way around the bottom panel, you’ll want to add a zipper at one of the ends so you can insert your cushion filling. Place the zipper face down onto the right side of the fabric at one of the ends of your bottom panel. Pin the zipper in place so that the zipper will be installed 1/2″ from the edge.
Watch the video below to learn how to install your zipper:
Repeat the process of pinning and sewing the other side of the zipper so that you have a functional zipper installed. Now you can sew all the way around the rest of the bottom panel (starting at the end of the zipper and stopping when you reach the beginning of it). Make sure to leave your zipper open a few inches before you sew all the way around so you can get back in later! Flip your cushion cover right side out, and you’re ready to add the filling!
Use a ruler and a marker to measure the appropriate width of your cushion filling.* If you aren’t able to buy a cushion long enough that’s in one piece, you just use as many pieces as needed to fill the cushion length.
*NOTE: I would highly suggest making the width and length of the insert a little bigger than your actual cover dimensions (maybe add an inch to both). This way the insert will fit snugly into the cover and you will have a full-looking cushion.Now, I’ve heard that some people use jigsaws or even electric turkey carving knives to cut foam and filling, but the thing that worked the best for me was actually a plain old handsaw. Weird, right? The saw was able to do most of the cutting pretty easily, but I did use some fabric scissors to clean up the edge a bit. Once my filling was cut to size, we folded the filling in half like a taco shell and inserted it into the cushion cover through the zipper opening. Use your waterproof spray to seal your fabric, and you’re done!
Throw in some outdoor pillows and a few concrete planters and your space is ready to go! Having these cushions on the outdoor benches makes the space look much more finished and one million times more comfortable. Once you get this cushion-making technique down you’ll be not only able to update your outdoor space, but you can also apply the principles to making cushions for lots of other seating options as well. Happy sewing! xo. Laura
