I've been alternating between several different projects this week. Thank goodness for multiple needle sizes!
When I'm not able to concentrate very well but can sit in one place, I'll work on my pink mystery socks. When I can't concentrate and need to be mobile, I'll work on a simple garter stitch shawl. At those times when I actually have peace and quiet, I'll work on my daughter's lace shawl. Finally, when I can't knit at all, I'll work on my shawl pattern at the computer.
Believe it or not, I'm getting quite a bit accomplished, even if the work is spread out among several different projects. I'm certainly not bored!
