I made a faux cathedral windows quilt out of my husbands old shirts & blue jeans.

I used 1 blue, 1 red, 1 green, 1 gray & 2 different white with stripes shirts and still have lots of fabric left over from all but one of the white striped shirts. It was meant to be a recliner cover so it's about 6' by 45" Hubby uses it folded in half to cover his legs at night. The weight keeps him from kicking me in his sleep.
