When I seen this in the "recent topics" I thought this was something else entirely. I have never heard of this type of swap but instead thought of "Hills like White Elephants," a short story by Hemingway that deals with a large, controversial issue. I was confused haha
Maybe one day I can try to make a custom and maybe someone will like it! I've not done a custom before and I would like to make one someday! Good luck and best wishes to participants!
