Power Mesh
"Power Mesh is an 80% Nylon/20% Spandex blend typically used to reinforce silicone prosthetics or for fixing tears in silicone. This material is a 4 way stretch material so it will move with the silicone, adding tear-resistance.
It is also an amazing material for impregnating in brush-on silicone molds to reduce tearing. Its universal stretch works in even the tiniest molds!"
