Rubber cut outs.

Another glorious material from Reverse Art Truck, Ringwood.

Just bought it to see what I could do with it and so far I've established they're staple-able. :)

Not overly fascinating so far, but I'm sure I'll find something to do with them. Melt them together, layer them, something. Really heavy and don't hold their shape, so obviously not something majorly 3D.

Sew them together maybe? Staples kinda look ugly, but maybe en masse they may not.
