You know..easy may just be the answer for this situation. This fall, all I could do, was knit washcloths. It's such an easy pattern and I've memorized it. The yarn is often on sale and available in all kinds of stores. (Such yummy colors, too). I could have been knitting a sweater but all I could handle were these easy little squares.
I teach and I have a particular challenge this year. Depending on how the day goes, my energy level is often shot by the end of the day.
