Check out this video from Stampin' Up for the "how to's" of using the paste. Just a couple of tips that I'm not sure are mentioned in the video. When you get your paste, the jar will only be half full. That is the way it is supposed to be. It settles in shipping. Each jar has 4 fl. oz of volume. It dries pretty fast so I would recommend keeping the lid on it as much as possible. Also if you scrape it back into the jar after using, make sure you push it all down towards the bottom of the jar. If you leave some on the rim, it will dry out. There is also a picture of using the paste on page 176 of the catalog.
Here is another card I made with the paste.
I used a piece of the glossy cardstock that I made last week with a reinker technique (see HERE) and another mask with the Embossing Paste and colored it with Marina Mist reinker. The leaves are from Vintage Leaves which also have matching framelits. To make the flowers multi colored, I did the Baby Wipe Technique. I dropped a few drops of reinkers on to a baby wipe, thus making my own custom stamp pad. The colors I used were Early Espresso, Lemon Lime Twist, Marina Mist and Soft Suede.
