I made a denim "crazy quilt" topper/ bedspread on my serger, even the binding. (Recycled blue jeans.) No fraying here! One was queen sized and one was twin. I added labels, pockets, etc. on the twin size - it was for a teen nephew. They are so heavy you have to be in the position you intend to stay in all night when you pull them up over yourself! They will last forever and 1/2!! :)
