I got a new Ikea Skruvsta chair this year, and discovered the seat is practically as hard as a rock (my other Skruvsta chair from 2013 is better padded…and rolls better, too). I had this beautiful fat quarter, which was just wide enough to cover the seat, provided I didn’t need any seams!
I couldn’t get any more of this fabric, so unless I was willing to use some other fabric altogether, I had to figure out a way to make this work.
I decided to use some red leftover cotton to create a sidewall/border, and some white scrap for the two pieces on the bottom. Winging it, really.
I began by tracing the shape of the chair’s existing cushion onto a piece of 22 x 22 x 2″ densified polyester cushion, then cut that with scissors, cutting through about half the thickness at a time. The 2″ stated thickness of this stuff is overestimated, and it also squishes down over time, so my plan was for a cushion not much thicker — if any — than the existing chair cushion.

Next, I traced the shape onto a piece of tracing paper, and cut out the top piece and the bottom two pieces at once.

I then cut a strip of 2.5″ red fabric for the sidewall, and two more 5″ wide pieces to trim the opening on the two white pieces.

I carefully clipped the long strip to the edge of the top piece, allowing the extra length to remain until after sewing, so I could make sure I didn’t lose any length to any possible mismatch from fabric stretching around the curve.

In sewing the two pieces, I had to adjust for some slack in the red fabric.

I then test fitted the two bottom pieces against the top and sides of the cushion cover.

I folded the bottom trim pieces in half before adding them to each of the bottom pieces, then ironed in another fold for a seam allowance on the loose edge, and sewed it down.

I made sure to line up the center line of each of the two bottom pieces with the the centerline of the top piece before sewing them together.

Once all the sewing was completed, I turned the whole thing right side out, and then pressed the seams toward the sidewall. I folded the cushion in thirds to insert it into the new cover, allowing/encouraging it to spring open inside the cover. I pulled the cushion into place inside the cover. A final smoothing of the cover over the cushion, and I was done.

Thanks to the use of scraps and a fat quarter, I can now sew in comfort and beauty. 😀
