I've been disappointed with the charm packs I've had. They were from Craftsy. I had a charm that I couldn't use because the corner was missing more than a half inch. And I had several that had curved, or not straight cut sides. Mostly, I disliked the pinked edges, which made it more difficult to get my seam sewn the correct size. This was especially annoying when sewing triangles (the charms cut diagonally), where the pinked corners on the right angles were sometimes there, sometimes not, and mostly all over the place for laying against a triangle I'd cut myself from a different fabric. I couldn't complain about any of it, as they were a free gift included with a quilt kit each time. But after seeing precuts, I prefer to cut my own charms or strips. Getting fat quarters is a different proposition, as I intend to cut those to the size pieces I need myself.
