Link updated 22 July 2012 ~ pattern is no longer available on the original site, but I found a copy of it (without photos) in the Wayback Machine's archives.
Whew!

Circus Elephant

A beautifully detailed amigurumi freebie from Better Homes & Gardens, this elephant stands 8in high and is 10in from nose to tail.

Skill level is medium.

I think I'm going to have to put up a glass-fronted shelf to display this one, and tell the kids hands off!
