Yoga Mat Bag from Old Pants

Step 6 Thread the drawstring and attach the strap

You're almost there! Thread the drawstring through the casing using a safety pin. Cut a hole along the casing on the on the outside of the bag. You can choose to embroider around this hole if you're worried about fraying, but it will only fray a little if you're using denim or corduroy, like me. Stick the two ends of the drawstring through this hole.

Turn the bag right side out and attach the loose end of the strap to the loose ends of the drawstring with the sewing machine. Be careful, as this will probably be very thick and could pose difficult to run through your sewing machine. I know my machine certainly didn't like it! Reinforce this seam.
