There are a few clothes that always seem to slip off hangers and end up on the closet floor. I wanted a quick, simple and inexpensive way to solve the problem. I found some e-grips tape in a drawer (Note: e-grips sells strips and tapes with a rubbery top surface and are typically used to keep cell phones and other devices from slipping) and came up with the following quick fix.
Step 1: Materials
Wooden hanger (should work with wire hanger as well)
E-grips tape (or probably any tape with a "rough" top side)
