Always a worry for us novice knitters, will it be square? My knitting is usually about as square as well, one of those potty mouth teenagers I so often have the pleasure teaching. I'm currently knitting a 20cm square for our school who are joining in a "Born to Knit" drive, making baby blankets which will be shipped to mothers in need.
I know this is no baby blanket, but I urge you to check out this sight for some very creative graffiti kniting. Hmmm, one day I might get beyond the square and start on a tree? Maybe it's more up my alley (or street).
I do love these street signs.
