t-shirt to trivet upcycling

What do you do with old t-shirts that you don't wear anymore? Ask Pinterest. I used this tutorial on cutting t-shirts to make yarn, which was super easy and fast, and I turned one old purple shirt that was worn out and had a couple of stains into a ball of yarn and knit a trivet!

 All I did was cast on 18 stitches on size 10 needle, and knit every row until I had a square.

 The t-shirt I used had side seams, so it's a little messy, I'd like to make more, but I'll have to make a trip to a thrift store to stock up on shirts. Over all I think it turned out well, very think and cushy, I'm not sure if it would work for a hot pad, I'd have to try out it's heat-protective abilities! :)
