It's thin paper with sticky adhesive on both sides. I adhered a piece of foam to one of the sheets and used the die to cut out the word. Instantly I had an intricate die word made out of foam. I peeled off one side of the adhesive and put a black die cut on top the foam. Then I peeled the adhesive off the back of the foam and affixed it to the front of the card.
You can see the dimension and strong effect that I wanted. In hindsight I would have used black foam but I'll do it next time. I heat embossed a sentiment onto a black cardstock strip and popped it up with foam too.
I left the inside very subtle for writing a message. So that's my second card using supplies from the card kit. There's more to come so look in again tomorrow. Thanks!
