Mom, stop reading this. I'll never hear the end of it... (my mom affectionately calls me Rainbow whenever I do something she considers crunchy or Martha when I do something crafty - and this qualifies as both) I have a lot of mis-matched towels. Are you with me on this one? You know, all of those random towels that you picked up 2 at a time because they were pretty and on sale but didn't match your current towels, or the stray ones leftover from your parents/roommate/ex that are perfectly…
