Only problem is it doesn't have a case. So far it's knocked around inside the big one from its predecessor. So, some math, drawing and stash diving later:
The outer is some lightweight twill leftover from Abigail's skinnies and the chairs is "Perfectly Perched" by Laurie Wisbrun for Robert Kaufman, from our quilt retreat.
No end of trouble stitching through the corners so it's not perfect, but it'll do the trick! I padded it with fusible quilt batting and also slid a piece of stabilizer (plastic milk jug!) in between the layers on the back.
Too lazy to go take another photo of my pattern... (sorry, phone camera pic)
I just layered the batting and then the fabrics right sides facing, stitched 1/8" around all the edges, trimmed corners and turned it right side out through a gap, and then stitched up the corners and edge of the case. In theory, simple, but the layers and batting made it bulky to work with. May have to try again at some point.
But I do love the chairs!
