Like I said, we don't have a tree yet so I hung them on the bonsai just to see what they look like. They are actually bigger than I thought which means that they'll stand out quite well amongst tinsel and other shinies...it that a word? Anyway, I just printed them on plain printer paper (not cardboard or anything) and once they are doubled over, they become quite firm:
Also available on the Cartoon Network site? Adventure Time gift tags. Its a good thing that appreciation of this show is a family trait otherwise I'd have some very confused family members on my hands come Christmas day!!
I haven't made these ones up yet but I think that I will probably stick them to some card before I attach them to gifts. Just to make them a little more durable. Yay for Christmas!
