I just want to share a fabric storage story ...
My mom sent me a box she had found in my closet from the home place.As soon as I opened it, I remember starting a bathrobe for my husband with that yellow terry cloth in 1983 (she sent it a couple of years ago). I know the fabric came from Fabricland in Astoria, Oregon... for those who don't know... damp weather, by the ocean and a big river so humidity is always a problem. The box was in my closet, but the room wasn't always heated. The box was cardboard. In the box was the terry cloth, little panels of clown dolls, and I don't know what else.
The point is: This was not top of the line fabric, stored in less than ideal circumstances in a cardboard box, which arrived again in my hands almost twenty five years later (I kid you not! 25 years!) Everything is fine ... This isn't the ideal storage by any means, but if it worked for 25 years, it shouldn't hurt your quilt top for a few months (or more :wink: ) The one thing I might do differently, were I you, would be to line the box with tissue paper, just in case the box has dust or whatever, and a sheet of fabric softener either in the top or bottom with the tissue on top of that to repel little beasties.
Ideally, I would go with a discarded tube from my local rug store, roll the quilt top on that and cover with a sheet. But, again.. there is that cardboard thing. I just have this hunch that as we have become "environmentally" more sophisticated, surely the products we deal with are better than what things were stored in, say, a hundred years ago?
