It's not worth the money but it is so much fun to do.
I got these done in Chinatown, in that huge shop that sells basically everything, 'oriental & cute'. I remember doing the stickers, but they don't do those anymore, and it's such a shame that these are even more expensive. We tried to pick the ones that made the least sense.
The individual photos can be found in this Facebook album, at the end.
I like this one best, but I love all of them.
