Hi, Anita! Thanks so much for joining in and posting a comment! You're the first one! I'm glad to see the board works!
You can order the instructional materials and designs from two sources: Wooly Thread or Talliaferro. Wooly Thread also carries the Appleton wool thread pack that goes with the design kit, but just so you know, right now there's a delay in getting all the colors of Appleton needed for this, as there was a break in production at the Appleton company for a little bit. They're catching up, but it's taking some time. But if you can get some of the threads, then you could start with whatever colors you have available, and then work with the other colors when they come in. That's what I'm doing - I don't have all the colors yet, either!
I'm not sure what design element I'm actually going to do - probably one of the smaller ones, though. Most of the techniques will be the same, no matter what element you pick, so I'd just pick the one you fancy the most. If you choose the large full "Persian Blossom," then you can always break it up into smaller elements if you want.
I'm really looking forward to this. It should be fun!
