Adding to the list of folks using the incredible https://openstreetmap.org to create neat stuff. It took a bit to figure out a process I liked; hopefully this writeup will be useful to others: Map-engraved / heart-inlaid coasters – Shutdown Hook

Hey Melissa — the second link in the post has step-by-step directions for using Inkscape to create the Glowforge files. I’d be happy to answer questions if you have any issues with it, I’m no expert but have gotten a ton of help from folks here so happy to return the favor! —S

The epoxy makes these look so much better than even finished wood. Yet another craft I need to pick up some day, or hope my wife does for me. Great job!

When I have used my Glowforge to cut cork in the past, I end up with burned edges that rub off black in your hands. Do you have this problem? I could use any tips. Thanks, in advance.

I am not the original poster, but when I cut cork, I simply wash it in water to remove any char. Cork absorbs heat, so it isn’t always the best material to cut with a laser.

Between the addition of the heart and then the finish … this is just so lovely!! Thank you for sharing your write-up.

At speed 400 / power 100% I don’t get much char on the cork, and a damp cloth or baby wipe gets rid of any that is there. The adhesive sheets I use are a relatively dense cork too, that might also make a difference. —S

Finally put together a simple but nice holder for these coasters! The dowels were purchased and the cuts were super-easy — two pieces of 1/4" maple-veneer MDF with overlapping holes for the uprights, dowels glued into place, 2mm adhesive cork on the bottom and a couple light coats of satin poly — not bad!
