Less working, more knitting

My first fingering weight scarf has been knit to about 15 inches. Since this will be for a fairly short individual, I don't think I'll need to make it much longer than 3 feet. I an very tempted to cast on for something else thought. I have discovered that my yarn cravings come from not being able to knit on something I really want to work on. I'm ok for the momnet since at least I'm knitting a pattern I chose, but I need to finish this one soon so I don't become tempted by more lovely fiber morsels.
