if I want to use embossing dies in my cuttlebug what do I ..

Another one who doesn't add anything for embossing. And I've used many different brands with no problem at all.

Scrapper100 I have a Cuttlebug and have to use the plates or some rubber sheets along with the die/plate to get it to make an impression or a cut. I think I had bought mine from PTI years and years ago though. Similar to this: www.amazon.com/Cuttlebug-Cricut-Emboss-Rubber-Embossing/dp/B00EV00C7G/ref=sr_1_2?ie=UTF8&qid=1442874880&sr=8-2&keywords=rubber+embossing+mat

It gets interesting to work with all the combos but I haven't had a die yet that wouldn't cut in that little green machine.

First you cut with the following sandwich:

White spacer plate, C plate, die facing up, cardstock, B plate. Add a cardstock shim on top before running it through if you need.

To emboss the cut, carefully transfer the die with the cardstock still in it to the following sandwich. You do NOT want to remove the cut design from the die to see if it embossed well. It doesn't. For the embossing:

White spacer plate, B plate, die facing up with cut design still in it, one or two rubber gasket embossing mats, then the B plate. Cardstock shim if needed on top.

It is usually a two step process to cut and emboss with the thin dies. The problem is that if the cut design slips or is removed and put back into place, it may not emboss correctly.

There is a company (Memory Box, I think) that recommends adding waxed paper to the die before putting the cardstock on for cutting, then add a very thin metal shim prior to the top B plate. That way cuts well and the cut design is easily removed no matter how detailed, but getting the cut to stay perfectly aligned (when you transfer to a B plate base and rubber gaskets before putting the second B plate on) is difficult.
