I made a pair of these (with my 3 year old assistant) in about 10 minutes, so cheap, easy and the puppy loves them!(I saw some in PetSmart for $7 each, and made my own for $1 each).
I did a step by step on my blog, but these were basically cut, tie, braid, tie, toss to puppy!
hmm...cant post a picture yet, the link is above! Hopefully I can edit and add one soon!
