Make a really cute bathmat from worn out towels

My favorite part about recycling is that it saves money!

I found this video and think it is fabulous!  Now to go find some old towels.  I can see some really cute variations out there using different colors to make stripes or polka dots.  Enjoy the video!  http://www.youtube.com/watch?v=KVhBfiy4XrM

Michelle Kauffman, the star of this video, has a blog with other recycle household ideas on it here:  http://blog.michellekaufmann.com/?cat=8

I have two wonderments about this bathmat.  1.  Can I throw it in my washing machine? (critical around here) and 2.  Will the nubs off the terry cloth lint off everywhere?  I think old sweatshirts would make a simliarly nice fluffy mat, without the pilling problem.
