Bethany S Reynolds wrote the book ( she's the one who originated Stack N Wack and was featured on Alex Anderson's show on HGTV) Her 1st book was "Magic Stack -n-Whack Quilts", her 2nd book is "Stack-n-Whackier Quilts" ( even more variations) they're very addictive, as I've made 4! after you pick your fabric you never know what it will turn out, and each block will be different... nothing boring about putting this quilt together! have fun !
