I am in need of a dishcloth, so I went rummaging through my stash yesterday for some Lion Brand Cotton that I was praying that I hadn't given away in a fit of pique. Thankfully it was still there, so I cast on for Kris Knits 'Be My Dishcloth'. It's a wonderful pattern; so effective and an easy knit as long as you don't accidently misread which row you're on! A ruler on the pattern certainly helps. There are lots of examples on Ravelry.
