Brown Bag Mystery Bonus Project Fabric Kit

Want to warm up before the mystery begins? Our Brown Bag Mystery Bonus Project Fabric Kit is the perfect way to practice, play, and build confidence before you dive into your Brown Bag Mystery quilt.
This optional bonus project is a pillow taught by the always-amazing Karen Montgomery. It’s designed to help you learn and test the same rulers and/or foundation papers you’ll use in the mystery quilt—so when the big reveal happens, you’ll be ready to sew with confidence (and maybe a little swagger).
