I am hooked!
I love looking at it for inspiration, as well as sharing neat things I find with others. For visual folks like me, it's a gem.
Tonight I assembled a Pinterest board of books for boys, recommendations from other moms as well as some of our favorites right now.
(My Pinterest page also has several other homeschool-related boards...as well as some just for fun!)
(My husband I insists I should backup my Pinterest images on Evernote in the unlikely event that Pinterest crashes and loses everything -- or simply dries up. He's probably right.)
