Personally, when I buy anything that is 3 yards or bigger I roll it on the cardboard cores - like in the quilt shops....I like to see my fabrics on display...small pieces like FQ's, and misc. cuts go in a cupboards or containers....
I just moved out of my house in October and so I lost my sewing room - it's not like this now...the larger pieces are all hidden in a closet - and the smaller pieces and FQ's are all in plastic bins.....I'm in a small appartment - and sharing - til I figure out where I'll go next...so I needed to adjust to the new space..but, when I get my sewing room back - I'll definitely have my shelves for my larger pieces/rolls...I love it....
I've never had a problem with cardboard, etc. - none of my fabrics ever got ruined......
