I used to run into them on juries at craft shops. Mind you, they were NOT quilters - just thought they knew what quilts should look like.
Mine are not the rotary cut, perfectly pieced, 3 matching fabrics type - more like folk art. Maybe all the strips in my Log Cabin block are not the same width, but it is sewn well with no major puckers. Going for an old-fashioned, scrappy look. But they wanted mine to "conform".
I always wanted to say, look at the pottery you have in the shop - some has smooth finishes, some has rough finishes. There are as many ways of making a craft as there are crafters.
Funny thing, though, my quilts sold quite well.
