I think ratherb was talking about when individuals buy antique quilts or blocks or things bought maybe at the thrift store and the individuals that purchase them will talk about how badly constructed or maybe even the colors. To me all quilts are beautiful. And as my grandmother got older her stitches were not quite the same, but still beautiful.
As someone else mentioned, people did not have all the toys we have now to make quilts.
I have never seen negative criticism of anyones personal work here on the board. I think we are all very supportive.
