Yoga Mat Bag from Old Pants

First project for the fame-off! In this instructable I’ll show you how to turn an old pair of pants (with a hole in the butt, no less) into a fancy drawstring bag for your yoga mat. I guess it would work for other long skinny things, too, like giant cinnamon sticks or a bunch of arrows. There’s also a Flickr set of all the images. Click extra hard to support the fatlab!
