I've had a lot of questions about embossing on cardstock, and I'm sorry it took so long to post this! Slow I know lol!
Here are 2 samples of embossing on cardstock. It works best on lighter weight, non textured cardstock, you do get more details that way. On the left side is running the embossing tip just once, on the right side is where I ran multi-cut 2. Make sure to click on the picture and view it full size.
