It came out a bit fuzzy as the paint was able to get under the paper. So I then laid down a couple strips of 18mm Tamiya tape onto a ceramic tile and cut the symbol out onto that. I then transferred it to the bottom of the clear base. I could have just as easy used a cutting board instead of the tile. Here you can see what was cut out and tape that was used.
Spraying the base white first puts the symbol onto the base. As you want to see the symbol coming up through the base, you must do this first. It's opposite of what is normally done, ie. spraying a design into a finished product. The top of the base was masked off and then black was sprayed onto the rest of the base. Give the finished bottom of the base a coat or two of gloss coat to protect it from the scraping it'll receive as it's moved across the tabletop.
You could do the same for others too such as Battle Fleet Gothic, assault troops, Tau Drones, or anything else using a flying stand.
