I was curious about using some embossing and etching dies I had. The first nine dies are meant for metal. I liked the embossing but not the etching dies. I ran them through a Cuttlebug machine (meant to be used for embossing paper for greeting cards) and they worked. I didn’t want to run the plastic dies that are meant for the Cuttlebug through my rolling mill – thought they might smush. So on day 20 I tried a plastic die, with metal, in the Cuttlebug and it worked without smushing it, which means I can use it over and over!
