After spending the week looking I have at last found my piece of paper with the web address for the original Bat template that gave me the idea for the class.
It is www.skiptomylou.org
The instructions and other idea's appear in a magazine called Woman's Day Specials, if you google womanaday.com/special it should come up.
I hope you have as much fun as I did making the bat.
We plan to hang them up on our beam in the living room.
