I'm making lots of dish/wash cloths in color coordinated bundles for in my Etsy shop. I've completed two bundles already, and have another half way finished and cotton for another 3 or 4 bundles ready and waiting. Should keep my fingers busy during the hot summer months!
Jack, you could use the same pattern that I'm using for my washcloths to make placemats...I used the woven stitch which I talked about here: http://www.hookedonneedles.com/2011/...ashcloths.html
It's a great stitch for a placemat because it makes a tight and flat fabric so things don't feel wobbly sitting on them.
Just a thought.
