These are made with a Lisa Vollrath pattern, from The Muse, Nov 2008 edition and Cosmo Cricket paper from last Christmas! I just love making these kinds of things!
The pattern is here: http://www.tentwostudios.com/
It's in the Nov 2008 edition of the Muse (not sure if the individual copy is for sale yet.) I've been a subscriber for almost 3 years and she has tons of ideas but does not allow pattern sharing, sorry.
