Instead of tossing all of those t-shirts that get frayed or don't fit you anymore, why not turn them into a blanket comprised of memories? You don't even have to sew it together.
Getting rid of some t-shirts can be tough sometimes. Maybe you have a great collection of shirts you got from various band tours, or maybe you have t-shirts that remind you of past teams you were a part of. Instructables user Dhopp1 explains an easy method for holding on to those memories while still getting some utility from them.
You can construct a no-sew blanket with nothing more than some cardboard, a pair of scissors and some time on your hands. You probably won't be able to toss it in the washer, but there are other ways to keep delicate things like this clean. For complete instructions, check out the link below.
