Just received these materials for my embellisher. Aren't they yummy? This will be really exciting to try out - I love the colors. It is quite interesting to learn how which material reacts to this kind of process. Even punching from the front or the backside of the piece makes a difference! And the way sheers react is absolutely not predictable. It all depends on the weave, the raw material, the kind of embellishing on the fabric itself. What astonishes me is how easy it is to felt fabric to wool. I love the effect of the fabric becoming kind of fluffy if you do the punching from the backside of the piece.
