I stock up and I mean really stock up at Hobbs batting booth. The 18" pre cut batting squares are super cheap! Wool, cotton, silk squares. If you see people carrying big pink plastic bags it's batting squares. I buy about six bags full the first thing and take them out to my car. If you don't have a car, buy them last . The bags are lightweight but very cumbersome to carry. They run out of the wool and silk faster, no matter the type it's all the same price, you can mix and match. If I remember right you get 20 squares for $5 or it could be $8. I don't even ask the price anymore, I just buy bags full. They are perfect for QAYG blocks, totes, projects, and small wallhangings.
