Many books are quite small now including do more great work by Michael Bunger Stanier and Manage your Day to Day edited by Jocelyn K. Glei.
Ont the other hand Decorate by Holly Becker of Decor8 is a tome.
Books one and two probably say read less books like number three but I will consider it research and inspiration! Much like Pinterest.
I look at very few quilting books these days but Art Quilt Maps by Valerie S. Goodwin did get my attention.
