I had an old t-shirt that I loved but it had a hole in it. I found a way to continue to enjoy it!
You will need Fabric Scissors/rotary cutter, Cutting mat, and a T-shirt.
Lay T-shirt flat on top of the cutting mat.
Cut one inch strips across the midsection of the shirt. Don't worry if they are perfect or not. You won't see the edges when you are all done.
Save the bottom strip and cut it open. You will use this later.
Stretch out all the other one inch strips then loop them over once. Matching up all the seams.
Wrap the last strip over the seams of the other strips until they are all completely covered and then tuck the end under
You can add a stitch at the end but it should hold just fine without it.
You are done. Enjoy your new necklace. :)
