Just a remix.
The wife loved the idea but she had issues with the letters falling off if she brushed against a letter or a hot beverage placed on the coaster and knocked a letter off. I did a remix, words , dimensions, then inset picture and words, set avoid crossing perimeters, inserted colour changes.There is a lip on the top outer edge that if you do not like just split at that point and delete.  Now there is nothing knock off as well as the beverage will sit more stable. Sprayed the top with a clear coat and the bottom with a clear rubber for good measure.
