I've got a palette of cotton and a one of wool and hooks of all sizes for the potholder swap crafting. At SnB on Tuesday I knocked out a sample, discovering along the way that I need to go down in hook size quite a bit. I liked the pattern I tried, but I'm still looking around.
I'm enjoying the experimental nature of this swap...it's nice to play with color and texture in a different way, and fun to pick up a hook as a change from the ol' sticks.
What are you working on that has you trying new things?
