I buy all of mine by the boa (on the rope). I cut a piece off about 5 inches long and then turn that into a snail shape. Then I hot glue the two pieces.
I then hand curl the strands that are not curly so the puff really does look rounder and fuller. I love Curly Ostrich, but I will tell you once you use it you will have feathers all over your house.
Here are a few pictures.

This one was not hand curled.
