My new bud Leigh OBrien is going to make and sell her fabulous color challenge books - go check it out!! The one she made for Splitcoast's 100th Color Challenge (pictured there on her blog) is GORGEOUS!!!
This would be a cool resource to have as she has ALL the previous color challenges each on it's own ATC card - plus the book! I'm still in awe over how pretty it is - I want one!!!!
Seriously - go check it out!:
