One of my first experiences with sewing - and recycling for that matter - was in 6th Grade Camp. Before we left each student had to make a bag out of an old pair of blue jeans. It was so simple: cut off a leg sew up one end hem and fold over the other and voila!
The other day I stumbled across this great post on Life Hackery about reusing blue jeans. You'll find links to 25 great projects - and like that bag from 6th grade some are so simple and yet incredibly practical and useful. My Grandma freaked out when I told her about Idea #1 - making draft stoppers for your doors out of jeans legs. I think that is what I am getting for Christmas.
Need further convincing? I'll give you four words:
POCKETS. FOR. YOUR. FRIDGE.
How cute is that? How seriously cute and practical and useful and cute? This makes me want to put pockets on everything. Visit Life Hackery for a link to that and plenty of other cool projects that you can make out of jeans.
