The photo below shows five of them "curing" with one coat of epoxy (just did these today). Four are mounted on pine "cookies", and one is mounted on a juniper "cookie". The green one in the photo was one I'd done earlier that turned out ok after one coat of epoxy. but one little dimple was left above the surface, so now it is undergoing coat number two. Will also need to give each of the others another coat, as well. Unless I actually route out a leaf shape and put them down into the depression, these leaves never lie completely flat even after pressing them between the pages of books for awhile.
This last photo is of some aspen leaves that were painted a metallic red. Waiting for them to cure, and to see if they'll be usable, too.
Just trying what I hope will be some interesting variations.
