I've had a couple quilts start to fall apart after a few washings. My seams are near perfect, finally. The only thing I can figure out is my lack of quilting.
In most cases, I cross hatch everything. These 2 quilts were put on my new sofa because of the dogs. They don't romp on the sofa but take a 50lb boxer that gets up there and walks in circles before laying down on 16" blocks with just a cross hatch-not good. So until I learn how to do FMQ, I'll echo quilt everything!
