I have quite a few old t-shirts from different events of the past several years. The sentimental part of me just can't bear to get rid of them, but I don't really wear t-shirts unless I'm doing heavy duty cleaning or really don't feel good. I found a tutorial on Pinterest based on this post by Dollars, Sense & More and decided to give it a try. It takes an old t-shirt and turns it into a cute tank top for work outs or days around the house. I'm really happy with how it turned out!
Find an old t-shirt. Pretty simple! My only suggestion would be to choose one that's a little big on you. I made mine out of a size small (I typically wear small/x-small) and I think a medium would have given me a little more room.
Cut around the neck, staying close to the original neck seam.
Cut around both sleeves, again sticking close to the seam.
Cut the front of the neck again, making it into a U shape with about 1 1/2 inches coming off at the center point. You should end up with a cut piece of fabric that looks like a smiley face. Also cut another 1 1/2-2 inches off the sleeves.
Cut a rectangle from one of the discarded sleeve pieces that is about 8 inches by 2 inches. Pull on the long ends until it rolls.
Tie the strip of fabric around the back part of the t-shirt. Wrap it twice, double knot it, and tuck in the ends.
