As I was web surfing for new ideas on Iris Folding I came around this site
Ten Two Studios and she is offering free printable sheets...
http://countdown.tentwostudios.com/
She's going to put one sheet per day starting December 1st until Christmas and all you need to do is put it on your blog...
If you have time please check it out and pass the word around...
I'm also going to put it on Card Maker http://cardmakermagazine.com
