This is a wax seal stamp I made for the Harry Potter Swap :)
I made it by making the shape from air dry clay, then letting it sit for a day. I used a pin to draw the "H" and Crest on the flat side of the stamp. Then I carefully scrapped away clay so there would be an indent where the crest would be. It took a lot of time and patience to get it just right, but it is so worth it :)
To make the faux seal, I just used my glue gun and pushed out a ton of hot glue, in a bug pile. Then stamped it with the stamp, and pulled it off carefully after it cooled for a minute. When the glue is dry you can peal it off the paper and paint it the color you choose. I did mine gold!
