I'm working on a log cabin quilt that uses 2 1/2" strips. It doesn't specifically say it's a "Jelly Roll" quilt but, it's the same size. I got two jelly rolls of Moda Portobello Market but I found that there wasn't enough of the light colors. Luckily I found a fat quarter set of just the Flax colors of that line on eBay. I am just about to finish 17 out of the 36 blocks (19 left to go) and I have only used 1 strip out of the second jelly roll just because I wanted that specific fabric. I cut strips from 6 of the fat quarters out of the Flax set and I may not neet to cut any more... I'll see when I get closer to done with the next 19.
