My fault

Well I have been working on Heather Bailey's happy stacker (http://www.heatherbaileystore.com/product-p/sp003-hs.htm) for my son for Christmas...not so easy!! I got the first ring done and then the post...YEAH!! Then I did the big ring...TOTALLY messed up!! I had to run to the nearest quilt store and YEAH they had the cogsmo crickets line and I was able to redeam myself with a new piece of fabric. Why are new patterns so hard??? I think I have it now...just three more rings to go!!! But I had to share my fuff-up!!
