A small hole in a shirt can be a frustrating problem, but it is one that can be easily repaired. There are a few different methods that can be used, depending on the size and location of the hole.
One simple method is to use a needle and thread to sew the hole closed. This is a good option for small holes that are not in a conspicuous location. To do this, simply thread a needle with a piece of thread that matches the color of the shirt. Then, insert the needle into the fabric on one side of the hole and bring it out on the other side. Repeat this process until the hole is closed.
