I have been concentrating on needle punch lately. Several years ago I was lucky enough to purchase a large lot of of Medici thread, just before DMC stopped producing it, and just before the rest of the world found out about it. It is a single-ply wool thread, wonderful for needle punch. You can use a single strand for details or multiple strands for background.
I sold the small skeins at shows, and they didn't last long. I tried selling the larger hanks -- at a really great price, I might add -- but no one seemed to want to deal with them. The hanks are rather unwieldy, and if you aren't careful you can end up with a snarly mess. Because I bought an odd lot, the colors were rather limited. So I over-dyed some of them and I'm making them into skeins. Aren't they pretty? They have yummy names like Bing Cherry, Vanilla Bean and Georgia Peach. Look for them in my etsy shop soon.
