How to display a beer coaster collection?

My sister Ariel is a big traveler and loves collecting beer coasters (like the ones pictured above from BuenaHelena) from places she visits.

Some time ago, we'd discussed her preserving them in resin so she'd have them forever. We brainstormed what she could use as a mold, and figured she'd need something to keep the ink from bleeding and suspending into the medium. That was a while ago.

Now, she has multiple shapes in her collection (making the mold situation more tricky) and has figured she really doesn't need THAT many coasters, if any at all. So she mentioned making a coffee table top. Good idea (I had similar plans for a vintage postcard collection), but, I had some other ones for her, all keeping with the resined-theme:

• If she ever buys her own place, she can make them into a counter top for a breakfast bar.


• If the resin wasn't too heavy, she could frame it and just turn it into wall art. The frame and resin would keep it from looking too frat house. This was her favorite idea.

I also Googled the topic and found this, which starts of good and ends on a facetious note. Still had some good ideas, though, including using them as postcards and luggage tags.

BuenaHelena, the blog the above picture is from, turned them into Christmas ornaments.
