Simply combine the following in a small container:
1 part glycerin mixed with 3 parts Alcohol
Use as you would any embossing fluid. This mixture will dry quickly without leaving a "greasy" residue behind.
Tip for embossing items on paper: Wrap a small board in aluminum foil, warm it by running a hot iron over it. (takes about 5 seconds!), set the paper on the warm board. It will raise and set quickly.
