Amusing mental picture here of you down on the floor with your quilt inspectors hovering around and on you. All I find under my cabinets is billows of accumulated dog and cat hair that has wafted down and under. And I vacuum every day. Somewhere in this house is another dog and cat that is invisible cause they have lost all of their hair. I can still see the current residents of the couch and chair and they still have full hair coats.
The 80s are gone forever along with quality. Perhaps that is why we all love our vintage sewing machines and cabinets, they were built to outlast us. Now things have a current life of, at the most, five years. I am currently working on an 1893 Singer treadle cabinet in which to put my 306. It has lasted 120 years. If it had been made of that particle board stuff it would not be here.
