Oh I am knitting washcloths too to practice my stitches. Although I haven't finished one yet. I keep ripping them apart.
I guess I am trying to make them perfect and not just practice.
I also thought how could I use this for cleaning after all my hard work.
Yes go to www.dishclothbotique.com
and they have like 5 pages of all different patterns that you can use for the cloths. They also have a picture of each. I like to see what I'm knitting so that I can hope mine looks like the picture.
Good luck can't wait to see what you make.
