if you draw lines on a piece of fabric (anything really), and sew a strip of tshirt to the line, in the center of the tshirt piece. go all the way down the line, as close as you want. sweep them to one side, and move to the next line -- I think I did mine about an inch apart . . . it makes a rag rug, and it is so easy! you can make the 'shag' as loose or as tightly woven as you'd like. I used an ugly rug, and 're-covered' it!
the quilt is gorgeous, as mentioned! =)
