Crafters use a variety of threads when sewing penny rugs and other folk arty crafts. There are many choices available: embroidery floss, wool sewing thread, and DMC perle cotton thread, for example. When I started making woolies, I used embroidery floss. Then the wonderful ladies at The Woolen Needle told me that they use either No. 8 DMC perle cotton thread or Valdani Threads (Valdani Threads are the premium threads for heirloom crafters!).
My personal choice is DMC perle cotton thread (No.8). In fact, here are some colors I just ordered from JoAnn.com because my supply was getting low. For some of my work I do use colored threads, but my main stay colors are black and DMC No. 642 (shown in the first photo, left). No. 642 is a great "blending" color and my choice when I prefer not to use black thread for my backstitching. I have a hard time finding DMC colors at local crafting stores, so I buy mine online at JoAnn.COM. They offer over 85 differ colors!
This weekend I finished a little spring pattern of my own design using some re-cycled wool and DMC No. 8 perle cotton. What do you think? :)
