"Your best teacher is your last mistake." --Ralph Nadar
Ah yes! The opportunity to learn comes at the most unexpected times. Creatively, many a mistake has lead to wonderful new directions that I might never have considered.
Now in knitting, mistakes with stitches are often are easily rectified, if you don't mind undoing what you've just done. This just happened to me the other night as I was knitting the socks you see above. I figure it is an opportunity to really learn the pattern and practice patience. (The pattern here is Anne Hanson's Almondine from Ann Budd's "Sock Knitting Master Class".)
