During intense exercising or playing a physically demanding sport, your clothes can often suffer. For gym shorts, the drawstring is often the first to go, whether it gets caught by a finger and broken or simply frays from constant wear and friction. But the drawstring is a crucial part of the shorts, anchoring them in position. Replacing a drawstring can be tricky, but fortunately there is a simple method to repairing it in just minutes.
Pass one end of the drawstring through the safety pin and tie it with a simple knot. Do not open the safety pin, now or at any time during this process.
Push the safety pin into the hole where the drawstring emerged from the gym shorts.
Bunch the fabric up around the safety pin, while anchoring the rear end of the pin (where the string is attached) at the opening of the shorts, and compressing the fabric that forms the "tunnel" over the pin.
Grasp the front end of the pin through the fabric and straighten the bunched fabric, pulling it down over the knot and the first few inches of the drawstring.
Repeat the process as many times as necessary, bunching fabric up over the pin, then pulling it along until the pin has looped entirely around the waistline of the shorts.
Untie the safety pin once you have removed it from the other drawstring hole. Even out the string by pulling the shorter end until the two are even.
