So, I never did anything with it, it was just sitting in a pile of UFOs.
This month's challenge on SewCalGirl's blog was presented by Ann Fahl, and she presented a tutorial about free-motioning flowers and leaf shapes. So I got out some black thread, made a quilt sandwich with this piece of fabric, and started sewing.
I outlined the flower petals, then did some pebbling in the centers. I used some YLI Soft Touch thread in black (the only black thread I had).
I think the large flowers look like peonies. Lots of thread tails to be buried still!
