Coaster build
What about it?
Coasters are foam sheet on bottom, then plywood, and gorilla glue to hold the ceramic chips down. Question is what can I use that will hold up to cold beverages to almost grout but fill in the gaps for the coaster surfaces? I can tape off the edges and use a lot more gorilla glue, was thinking clear caulk but it would be harder to spread, not sure how spackle would hold up, and have zero epoxy experience.
The wood part was easier, just 4†squares glued and pressed to foam craft sheets.
