We moved last year and needed to put a lot of things into a large storage container. That included all of my fabric and sewing supplies. I had everything in plastic bins that were stackable, so hopefully it all would be OK. The container was stored for 5 months in a yard somewhere in full sun. I was almost afraid of what I would find when opening the container, but all was well. The fabric and supplies were none the worse for wear and not a sign of a bug or rodent anywhere. The only casualty was a couple of the bins broke- the movers had piled them too high and the weight cracked some bins. No big deal- now I have everything in a wall to wall cabinet in my new sewing studio.
