How to sew boxed and welted cushion cover.

This boxed and welted cushion tutorial is best supplemented with the video at the end. It’s much easier to show the process through video than to tell the process with still pictures, so make sure you check out the video. Sewing a boxed and welted cushion cover seems like a daunting task, but once you know the steps its actually quite simple with only 5 parts to the equation…the top and bottom platform, banding or boxing that goes around the edge, the zipper panel, and the welt aka piping. 1. The first step is to measure and determine the size of your cuts. I cut all my pieces with a 1/2″ seam allowance, so 1″ larger than the finished size of your cushion. I have a video tutorial on the best way to measure for a cushion cover here.

Once your top and bottom pieces are cut, attach your welt with pins and sew the welt to your top and bottom platforms. I have a welt making video tutorial here.

2. Cut your boxing/banding pieces and assemble the zipper panel. I have zipper panel tutorial here. At this point you want to cut V notches to mark the centers of all your pieces. You do this by folding your pieces perfectly in half front to back. On the fold you cut a small notch making sure you don’t cut into the stitches. When you open up the piece you’ll have a perfect little V cutout. This makes it easy to line up all pieces correctly, so you’ll have perfectly square cushions.
3. Pin the boxing piece all the way around your cushion bottom platform making sure to line up the V notches you snipped in the centers of each piece to ensure you cushion is square. Then pin on the top platform piece the same way. 4. Sew the cushion together with your zipper foot or welt foot. Almost every sewing machine has a zipper foot and you simply run the zipper foot as close to the welt as possible. 5. The last step is to attach the zipper panel. You treat the zipper panel just like the boxing. First you sew the zipper panel to the boxing on each end, then you line up the center notches of the top and bottom platform to the notches in zipper panel, and then pin it all together. The only part thats a little tricky is the corners and creating the pockets at the edges. Make sure to watch the video for this part. The last step is to turn you cushion cover right side out and stuff your foam into the cover.
