I thought that I bought some purple thread recently to use on this, but if I did it's lost in my cluttered sewing room. Or maybe somewhere else in my house. Who knows? So I dug out some variegated thread that was leftover from a quilting project and used that for the blanket stitching around my Dresden Plates. Maybe it was a happy accident that I lost the other thread, because I really like the result.
The applique is all done on this and maybe over my lunch break today I can go to the LQS and look for some border fabrics . . . because my stash had nothing large enough to use.
