Fray Stoppa is a must have product! It's a solvent based anti-fray adhesive specifically designed for use in the binding of fibres to prevent fraying of fabric hems and seams. Resistant to normal washing and will not damage the plastic componentry of sewing machines, excess can be removed with DD eucalyptus oil.
Fray Stoppa can also be applied to the back of buttons to prevent the thread from coming undone. It can also be used to stop runs in pantyhose.
