No surprise there. Have you considered a letter to the editor, or to the article's author?
Last year a nationally-published cross stitch column by Nancy Thomas, "The Needleworks", advised against cleaning cross stitch. She also recommended mounting on sticky board and framing with no glazing.
Several framers responded to Ms. Thomas, and she printed at least two of the letters decrying her advice and giving the reasons why cleaning, glazing, and non-invasive mounting are recommended.
So, the hobby-stitching industry may not have anything against proper framing, but it seems they are simply clueless.
As responsible framers, I think part of our job is to educate consumers whenever and wherever we can. It's a win-win situation -- we get more business and they get better framing.
