Here's a quick little recycled-clothing tip I discovered just the other day.
Because of all the things I make with t-shirts (quilts, baby clothes...), I have a lot of spare t-shirt sleeves lying around. I got the idea to cut these into 2" wide vertical strips. Pull on them so the cut ends curl, and TA-DA! You've got a perfect headband! I love these because they keep hair out of my face, dress up a plain braid or pony-tail, but don't put pressure on my head or pull my hair like elastic ones do.
So far I've made these sleeve-bands in hot pink, black, white, and red, and have worn one just about every day! :) Eowyn always smiles at them in my hair, and wants one on her head, too.
Pic to come.
