I want to make some coasters, but I’m not sure how to go about it. My prototype has a problem.
I created the art with colored pencil and technical pen on paper. I glued the paper to a cork disk with spray glue. Then I covered the whole thing with a clear resin. The problem is twofold –
1) The resin soaks through the paper, thereby making it translucent and dark against the cork
2) The resin dissolves the glue, bubbles form under the paper and it floats towards the surface a bit. The bubbles are formed as the resin hardens, not as a reaction to the glue.
The main problem is the first one. I think that if I let the glue set longer, I’ll be OK. I have come up with a couple of crappy solutions. Hopefully, you guys will have better ones.
1) Coat the paper with something. Clear paint maybe?
2) affix an opaque backer to the paper…but I have no idea what to use.
What are your thoughts?
