Yarn Shopping at Home Depot

Recently there has been some discussion on the knitlist of knitting with Mason Twine.  It is a smooth nylon cord sold in spools of varying yardage.  Intrigued, I picked some up when we went to Home Depot today.  It comes in neon orange, yellow, pink, and even rainbow.  I played it safe and got white though.  I almost got the hot pink, but I just couldn't picture myself carrying around a beach bag that color.  Maybe I'll get more adventurous if I find that I actually like knitting with this stuff.  At any rate, I never expected to be looking for yarn amongst building supplies.
