I forgot to mention that I used loom clips as I was knitting the practice sock. Using the clips was easy... SNAP! and they are in place. But unsnapping them must be done carefully. I was concerned that I might break them as I twisted them off, but I didn't.
I am almost finished with the second leaf for my poinsettia. I'm still struggling with the yarn being wrapped too tightly on the loom, so I have to find that "perfect" balance to knit with. The two main problems with the yarn being too tight are: 1. sometimes the peg pops out of the loom while you're trying to pull the yarn over the top of it, and 2. sometimes the yarn you are trying to knit over comes off as you are trying to knit off. So both strands of yarn are left dangling while you try to figure out which one belongs on top. ARGH!
