This Cheryl Phillips website. The book seems to be about the same price everywhere. Usually Alibris has books a whole lot cheaper, but not this time.

By the way, anytime you're looking for a quilting book it's probably worth checking Alibris. I live in Canada and bought 10 quilting books at a go from Alibris. I paid $65.00 total and believe me the shipping was a whole lot pricier than the books. I think the books came to about $25.
They also have lots of 'free shipping' items especially in the US. Good luck! The book you're looking for looks great. I'll be checking out her website more carefully. Thanks!
