For the second set of 3 cards, the kit uses a paper from Simple Stories. I don't even know this company, but I do like the paper. It is brick red with big white dots on the reverse. Here is the sample for the card:
The original has vellum in it, too, so I'm sorry that I didn't get to use it, but I have enough "Thanks" and other paper to make another card, so maybe I will.
