While vacationing in Colorado, I spotted this very easy to make t-shirt scarf. Below, you’ll see it in black, pink, and blue.
It’s just a strip of t-shirt fabric. Do it yourselfers could take a couple strips from an old shirt and sew them together for length. It’s unfinished (no hem) so the strip just rolls into itself. The “pendant” is just a string of beads. Two large beads border the pendant, and can be positioned in two different ways, as shown on the card:
This could easily be an upcycle use for t-shirts. Another idea for more of a necklace is at Bargain Babe. And if you crochet, look at Mandy’s idea.
