Instructions for the Non-Slip Wig "Sew-in-Yourself" Kit
This non-slip material (AKA artificial skin or non-slip skin) comes in 11 strips of varying widths & lengths:

The strips are to be sewn into the underside of the wig cap, using the template (see hand-drawn diagram above) for the strips placement.
Since each wig cap differs, you can cut these strips to match the correct area of placement on your own wig cap.

Most of the strips are to be sewn into the perimeter (outside edge) of the cap, while the smaller thinner strips should be sewn alongside the inner wefting area (if applicable) of your wig cap. The medium strips should be placed along the ear tabs, The larger strips should be placed along the front & bottom (nape) section.

*When sewing these strips into the cap, it doesn’t make a difference which side of the non-slip strip you use.

Use a heavy duty nylon type of thread, with a dense needle in order for it to go through the material and the actual wig cap.
