I am working on a queen size jelly roll quit right now, that I have decided to do QAG in 12" finished squares. I cut the 12" inch squares of batting and backing and sew the jelly roll strips along the length oeach block. Do start in dole of each square so I do end up wth extra width to trim on the sides, but since it is for me, I am OK with that. Visually is appears even on the sides because I am only trimming a little. I am putting it together with a contrast sashing in a "rail fence " arrangement. I will post it when it is finished.
