This morning I decided to get on and do the stool.
My fabric offcut wasn't quite long enough.
I considered waiting for the fabric for DH's chair to arrive. And then I decided that I would use the side bits cut from my chair's cover, to extend the piece I had.
I carefully, painfully, pattern matched and pinned. The fabric was right side to right side but, as I have limited spatial awareness, I could not turn it round in my mind's eye to work out where I had to sew to ensure it would work. I had to do some tests on some scraps to get it right, and then apply that to the real fabric.
Whatever I did, it worked BEAUTIFULLY. Very pleased. Wish I'd taken a pic.
I then managed to get the seat cushion covered fairly quickly, without any instructions. Bish Bosh. Well, ish.
I didn't pin it all in one go. I pinned a but, then sewed, then checked, then pinned another bit. This gave me a bit of a problem when it came to sewing the second (and third and fourth) bits, but it was relatively quick and painless.
I applied some of my learnings from the chair, and was pleased with the result.
Just the horrible chair to go.
