Tie Dye Washcloth

I recently bought a tie dyed t-shirt at the goodwill for $.99. I took it home and cut it into strips that were roughly 1 inch wide.I used size 19 knitting needles and simple garter stitch to make this rainbow washcloth. I had originally used size 15 needles and it was just to tight/dense. It still seemed a little stiff, so I threw it in with the laundry and boy did it shrink (it must have been a new shirt). I was able to stretch it back into shape. The garter stitch has given it a lot of texture, it will make a good dishcloth or swiffer cover.
I have read that using well worn t shirts makes super soft washcloths, new ones not so much. I think maybe I cut the strips to wide, I'll try 1/2 inch wide next time. I already have a nice worn shirt ready to be sacrificed.
