this is about the pinching ones.....my husband made me one and it's a pain in the neck to change quilts. you have to hold the new quilt up straight while you're pinching or it doesn't hang straight and then you lose the top edge of your work. when you hang it up it's heavy and your arms get tired.
the better one he made for a different wall was this. he got nice wood, stained it to look like woodwork. screwed a backboard to the wall painted white to disappear and used brass screws to attach the 'woodwork' board to the white board at both ends for feature hardware. it hangs butted right against the ceiling where woodwork would go. he made the whole thing 10' long. i'll never hang a 10' quilt, but the board sticking out looks planned and like an accent. i slide the 'woodwork' board through the sleeve and it accommodates every size. it's nice because every time i finish a quilt, whatever size, i get to see it a while before it goes away. at the change of seasons. i put on whatever one i'm not using. i love it.
