I love to use the Idiots Washcloth Pattern because you knit on the bias and it's garter stitch all the way with a simple edging you get by yarning over at the start of each row. So it's a fairly quick knit and doesn't require a lot of concentration, which is a nice break sometimes. If you enjoy quick knits I highly recommend the pattern. I use Sugar and Cream cotton yarn for these. I'll sometimes make larger versions and use them as face and hand washcloths too.
Anyways- I have a treat for the those who enjoy a little British humor. I think they're really quite clever!
