Here is what my little bottle of Outdoor Modge Podge looks like:
It came from a sample pack of Modge Podges (glossy, matte, sparkle, acid free, and outdoor). It is still waterbase, but I assume it would be more durable than normal Modge Podge. Hopefully I'll try it on my own coasters very soon!
Thanks Emilu for showing me. I'll have to keep my eye out for some. I knew about the glossy and matte kinds, but that's it. Very helpful! Good luck on your coasters!
I love this!! Where did you get the maps if you don't mind my asking?? I would love to do this.
Oh I don't mind at all. I actually just did a Google search for "Treasure Maps" and another for "Pirate Maps". You have to really dig for good pictures (most are from games or hand drawn it seems) but they're all there. I didn't keep the actual links, but I did keep the images so if you run into trouble let me know and I'd be happy to email them to you.
