We didn't have any holiday themed coasters, and instead of buying some online (given there weren't many great options), I decided to design some instead. At the time, I didn't have the ability to print multi-color, so I had to print each color separately and insert them together. My slicer and printer tolerances could probably have been more fine tuned, but they did fit snug. The pictures show a red base with white insert, but you could obviously use whatever colors you wanted. Green and Red, Green and White, Purple and Gold, your options are unlimited. If printing multicolor, the finished product will probably come out even nicer since you don't have to worry about fitment tolerances. I also added a little adhesive backed felt so that they don't slide around on smoother surfaces, and it gives them a slightly higher quality feel. I recommend a higher infill or more heat tolerant filament if you plan to have hotter drinks on them for longer periods of time to avoid any warping, as is to be expected if you were to print with something like PLA and expose it to hotter temps - that said, they original PLA ones I printed have held up super well over the past few seasons, especially since we are only using them for a couple months at a time.
