Just as a precaution, the fabrics you have in plastic totes I would also put them into a plastic bag too. I had my sewing room in storage for 4 years by what I thought was a good company and when my stuff arrived, most of my plastic totes were cracked, bowed out of shape, etc. All was supposed to be in an A/C storage unit but when I noticed some of my small appliances and even one sewing machine that had been white when it went into storage was now yellowed which makes me think it got hot inside the unit. Anyway, I was fortunate that my fabrics or machines were not damaged due to the totes being destroyed.
