Here is my version on these awesome Owl Post Cards! I left mine blank so my partner for the Harry Potter Swap could address them to her friends :D Also I made a Wax Seal Stamp with the Hogwarts crest on it, in a different project. I made the seals using hot glue though and then I painted it gold. That way you just have to add a dot of glue to where you want to place it on your sealed envelope!
I love these cards and I am so glad Andrea shared them with everyone :)
