  • Interesting. I assume that this material would be under a glazing(glass or Tefzel). I would be concerned that the dies and the material itself would disintegrate over a short period of time.

  • Fading is a reasonable concern but I've been exerimenting for over 2 years without a problem. The felt is made from recycled soda bottles and the black pigment, whatever it is, is very stable.
