Here's an update on the chair.
This is what it looks like right now. (And what it's looked like for about a week.)
And here's the fabric I chose, pinned and ready to sew the first piece (the inside of the right arm). Of course, the trickiest piece comes first. (Dear Kate, thank you, thank you, thank you, for the tip about PrudentBaby's how-to's. I followed the instructions exactly for piping, and it worked beautifully!)
I got this fabric for $6/yard. Originally $24/yard.
That sound you hear is me, patting myself on the back.
