Also, how do I measure how many jelly rolls I need for the Irish Chain? If I do 10 inch blocks and use all 20 of the SBS, the inside of the quilt will be 5 vertical and 8 horizontal blocks, measuring 50 by 80.
I've already bought one jelly roll of the snow. I also bought a jelly roll of the grunge solids, but I may change my mind base on the advise on the board. If I buy a simple vintage print jelly roll, how many should I buy?
