A while back I wanted a portable but sturdy gaming table so I bough some 1ft X 1ft wooden boards from Michaels and spray painted them with textured paint. Now, I used the other sides for an Armada Table. In case anyone wants another way to build a table, I hope I can give some inspiration. I spray painted all the boards black and then "flicked" some white paint on them with my finger for the stars.
The nebulae were created with different colors of pink, blue, yellow, and white spray paint with some pastels smeared in to smoothen and blur the nebulae. Lastly, a spray matte varnish was used to seal in the colors. The varnish would sometimes blow away the pastel so multiple "smearing" was required until the colors blended.
The planets and nebula pieces were created using this as inspiration: spray painted planets
I'm actually pretty happy with how it turned out and I love that I can rearrange the pieces however I want to. It's also very portable.
