T-shirt necklaces have been our list for some time.
This is a five-minute craft. All you have to do is grab some old t-shirts, a rotary cutter, and a cutting mat. According to fabric whiz Cynthia Treen, if you want the fabric to roll, you'll want to use a single-knit t-shirt rather than double-knit.
I can't tell you the difference between single and double-knit until she texts me back. I just know, for now, that most, but not all t-shirts will work. Start by slicing the shirts (across) in one inch strips.
Make a bunch. Stretch the loops and they will curl up into 1/4" strips.
Loop them, braid them, add charms, knots, whatever you like. It's incredibly flexible and always looks amazing.
They even have man potential. Just be sure you call it a "scarf" not a necklace.
Thanks to T. and T. for the idea.
