http://pintangle.com is the site for the Stitch Challenge.Here is the Drizzle Stitch-very organic and fun. The left one is a metallic twist of three threads and worked fine. The orange is a heavy Perle type thread. The green is Perle Cotton #8. The yellow is a silk. The last one is an ombre cotton knitting yarn that's a tube.
I learned that using a tapestry needle was a good idea. I work on my lap and poked myself with the sharp one. The needle needs to be large enough to let the thread go through to anchor the stitch. Also, don't wrap the thread so tightly that you can't pull the needle through.
