When my sweet baby brother started college, he had a ton of t-shirts from all his high school teams.
Choosing the most interesting of each t-shirt, I backed it with stabalizer and cut 12 x 12 squares. I cut an equal number of squares in red and blue (his new college colors) and sewed them together.
Then, using red yarn I hand tied it through batting and backing, placing a tie every six inches.
At that point, I ran out of time and took it to someone a little more speedy to finish up the edges.
