2014, I purchased flannel fabric in one to three yard lengths. Each Days for Girls International kit includes 8 reversible, tri-fold, flannel pads. My strategy included sewing pads from 8 different colors and patterns for each kit. By year-end, I had over 30 types of remnants. Variation due to cutting, shrinking from washing and fabric width created a significant amount of remnants in strips and block shapes. I recycled these scraps into two light weight blankets.
In the three years since the original post, I tightened my strategy on purchasing flannel to reduce the waste (given my experience with shrinkage and end of bolt pieces). The most significant change was to buy 4.5 yard lengths. My 2017 striped flannel piece represents is a reduction of over 75% scrap.
