I used light cardstock with double sided tape and a glue stick. I mostly used the tape for the "body", and glue for the head and the feet. I suppose if you only want to use one or the other though, your best bet would be to use tape for all of it, it will hold more securely. As you can see I also put the heads of the characters on different places on the body. If you were to tape most of the head flat on the top for traveling, you could curl the rest of the head up a little when you get there. This might save you some time. Good luck, it was really fun making them!
