I'm using a large canvas painters cloth, my felted wool scraps, and cotton embroidery floss. I cut the canvas cloth in half to save to use for lining the back. Have to have something to cover up the back of my stitching. Not to mention that every southern girl is taught by their mothers that you simply must have a backing to your curtains. Heaven forbid.
Here's a picture of some of what I have so far. I hope it looks kind of boho crazy gyspy carnavalish meets the Borrowers and the Weasleys....because that IS what I'm going for.
I made up the pattern myself, and hand dyed and felted all of the wool. I will finish this project too...eventually. Dangit!
