One of the best examples I've ever seen of using non-knitting designs for knitting is Catherine Devine's Sock page. Her Celtic socks are terribly inspiring and I already have the Celtic Charted Designs book she got the designs from. I need to get out my graph paper and colored pencils and make some charts for future mittens. The Harald mittens from Viking Patterns for Knitting in Tahki Sable wool/angora will be finished today and will go in my knitting box waiting for someone to fall in love with them.
This weekend I hope to do some tvaandstickning and report back here on my experiences. I'm sure you will all be holding your breath!
