I forgot to mention that the 12 yards was in 7 different fabrics, 5 pieces 2 yds each, 2 pieces 1 yd each. I don't use cardboard (cockroach food) or plastic to wrap my fabric on because it takes up space. I fold my fabric lengthwise (center to selvedge), wrap it on the ruler, remove the ruler, and stand the fabric on the shelf. When I buy any where near a full bolt I just store it on the bolt even though I hate having cardboard in my house.
I just mention this because we have so many posts about ruler folding fabric, and we always talk about using the 6" ruler. This board is where I learned it. Of course there are many ways of doing just about everything, and the ruler fold is what works for me. I don't know why it took me so long to realize I could use my wider ruler. 6" worked great when I kept my fabric in dresser drawers, but using the wider ruler I can put more fabric on my shelves and not have any that I can't see.
