I just finished up these coasters, as a gift for the founders/co-hosts of our local board gaming group:
(I’m sorry for the phone photo / lighting quality. The background colors are more vibrant that the photos would suggest. Also, the last one isn’t an etch; it’s a cut backed by black foam.)
- 3mm Baltic Birch ply
- 2mm EVA foam
(For the specific material settings I used, see my companion post in Beyond the Manual: Birch Ply and EVA Foam Coasters)
I also considered cork backs, but I preferred the ability to mix & match the background colors.
I don’t suspect I learned much that others don’t already know…
It was a lot of work to get the cut patterns just right within the meeple shapes, but ultimately a fun learning project. I certainly got plenty of practice with the path manipulation tools!
I’m sure it’s material-specific, but there was definitely a threshold level of detail to dial in, both in terms of extremely thin lines being too fragile and thicker lines hiding too much background.
Coasters get wet, so make sure the finish and glue/adhesive can handle it.
