i KEPT MY FABRIC FOR YEARS ON BOLTS. nOW i HAVE FOUND THAT AT THE THIN EDGE I GOT WHITE LINES FROM THE CARDBOARD BOLT.
NOW I USE THE PLASTIC FOLDING BOARDS. I GOT THEM AT POLARNOTIONS.COM
THEY ARE A BIT EXPENSIVE BUT THEY LAST FOREVER SO I DECIDED THAT THEY WERE A GOOD INVESTMENT.
I NOW HAVE MY STASH FOLDED ON THESE BOARDS AND HAVE THEM STANDING LIKE BOOKS IN A GLASS FRONT BOOKSHELF.
