Locate the damage.

This repair type is meant for small to medium holes approximately 1 inch by 1 inch (~25 mm by ~25 mm) or less in size.

For the most invisible repair, choose a yarn or thread of similar weight, color, and materiality.

In this tutorial thick embroidery thread is used because the repair is to a mesh backpack pocket. On a knit garment such as a sweater, yarn would be a better choice.

Draw a square around the hole about 1/4 inch (~6 mm) bigger than the damage on all sides.
