Of course knitters, in their inevitable push to use knitting to make just about anything, would come up with a way to deal with bad hair days. Here's a few free and very affordable knitted wig/hair-like patterns. To start with, Louise Walker is a very talented English photographer and knitter. Although she's just finished art school she's making a name for herself by using both of her refined skills. One of her more unique creations is the knitted wig. Here's a couple of examples of this work. Louise designs, knits and then photographs her wigs. According to her website (check it out for more photos) these Woolly Heads are inspired by famous and/or classic hairstyles from the past and are a nice change from the usual winter hat. But I think they might make for very interesting Halloween costumes as well. Or how about an Elvis wig for the male in your life who just can't wait for his own hair and mutton chop sideburns to grow. I particularly like
Getting it together one stitch at a time.
