They look like shaggy dog hair and were perfect to use for the puppy ears!
Here is a picture of my daughter "posing" with her puppy ears. Once we paint the tips of their noses black and add freckles, they'll look just like puppies!
A couple months ago, I found these black bowls at IKEA for $0.49 a piece... you can't beat that price! I bought 14 of them and I *think* I'm going to use them to hold each guest's dog collar craft supplies (will explain dog collar craft below).
The guests will make a dog collar for their new pup using stretchy cord, colored beads, and a metal rimmed key tags (refer to picture if you have no idea what I'm talking about) for the puppy's nametag.
