t-shirt yarn

I am not much into crochet, and I don't knit at all, but I couldn't help trying out making some t-shirt yarn using this tutorial when I was culling through hubbies t-shirt stack this morning.  Anything with holes or stains is getting the scissor treatment!
3 balls of 'yarn' so far!

Now, what will I make with them?  I have NO clue.  Maybe a rug for my camper?  It would be nice to have a 'custom' sized rug to fit the drop-down area.......  we'll see!
