To start, I measured the length of fabric that I would need to wrap around each end of the mat and leave enough slack in between to go over my shoulder. I did this using twine. Then, I cut two pieces (in order to get the appropriate length) of fabric about 6" wide. These two pieces were then sewn together to create one long strip.
In order to make the edges of the strap finished, without turning it inside out, I folded the fabric in half, ironed it, opened it back up and folded each edge into the middle. I ironed the outside edges and then folded and ironed the whole length one more time. To create a finished end, I carefully tucked each end in.
I sewed around the perimeter of the strap, taking extra care to make sure all of the fabric was tucked at the corners. I then made loops by folding each end down and sewing it in place. Large ring clips fit perfectly on each end.
The strap easily loops around each end of the mat and when it is lifted the weight of the mat keeps the strap secure.
This strap was so simple to make! All in all, about 30 minutes! I love that it is small enough to toss in a gym bag or even your coat pocket during a yoga class, and my sister in law loved that it was made just for her!
