I packed up my sewing room...machines, fabrics, etc. in either their original box or in plastic totes. All was supposed to be stored in an A/C storage facility but I'm sure it was not as some small appliances, etc. had turned yellow which I think is caused from a hot environment. They were stored in there for almost 4 years and this was in hot, humid Florida. Nothing was damaged or unworkable excluding the discoloration of the appliances.
