I agree, and will not buy pre-cuts any more. I had bought these before I read all the horror stories about the stuff in fabric. I also worry about runs, as I've had red fabric that refused to quit bleeding, wash after wash...
Thank you Prism for explaining it's the weave of the cloth that causes them to shrink more in one direction, that is exactly what happened. Maybe they should cut the charms and layer cakes on the bias?
