I made some with my nieces and nephew last year for their parents anniversary. I think I bought a kit at either Hobby Lobby or on ebay. I think I saw them at the store and then bought it on ebay. It came with little stones and little chips of stuff to decorate them. I don't have pictures on this computer of them though. In the kit was just a plastic form and some sort of concrete mixture. Once you have the form, you can get your own concrete to use and then whatever decorations you want. You can also color the concrete mixture to make different color stones. The kit I had came with letters you could press into the mixture. Then I had the kids paint inside the indentation. They spelled their name and age. They also put their hand print in the wet stuff. Then they each made a picture with the glass and stuff. One made a butterfly, one did a baseball and I forget what the other one did. I wish I knew where I put the kits. Let me look on ebay and see if I see a similiar one. Here is a kit that is similiar.
