I thought that elongating the Giraffe back of the hat would give a sense of tallness.
The Elephant is also glued onto a blue $1 store hat. I also put boning in the front of the Kangaroo's "pouch" to make it stick out a bit. We had to make multiples of several of these costume hats, so it has been crazy with fleece scraps around here!
Thanks for letting me brag!
