Pinked edges never bother me. I don't really see them when I put the fabric together. I start sewing from the point, the distance is so tiny between points it is like sewing straight edges. Batik jelly rolls are the worst at being off size. I don't buy those. So far I haven't had any of the Robert Kauffman jelly rolls be off size so that is the brand of jelly rolls I buy. I prefer layer cakes in pre cuts and buy a lot of those. I have the 2 1/2 strip die and use that a lot to cut scrap fabric for string quilts.
