I posted a nice long reply last night and it went into cyberspace.
The ink is an "ink pad" like you use for stamping. It actually says "chalk ink" on it. The brand I have is Color Box and I get it at a local shop but I'm sure they have them in big craft stores.
You open your embossing plate and "tap" the ink pad right on the plastic. ONE SIDE only. Make sure it's on the side that will leave the "raised" imprint. The paper will pick up the color and the raised parts will remain the cardstock color.
Make sure to clean you embossing plate.
Do you have any stores near you that give classes? I think a person gets more for their money when you take a class. You really get to learn more options and I highly recommend a Cuttlebug class.
I love my Cuttlebug so much that I have a container of already-done pieces ready to slap on cards. I just need to send more cards! 'smile'
Have fun!
