CB - be very careful when choosing storage, even for your furniture.
I stored all my household goods (crystal, dishes, etc.) for a year in a garage-type storage place without thinking it through, never having done this before. It was easy to back up the U-Haul and load/unload the boxes!!
There was no heat, so things froze and then thawed, and some delicate items cracked. And -- there were "critters". Even though all the clothing was stored with cedar hangers, cedar blocks and sealed in heavy-duty garment carriers, the collar of a Chanel dress was gnawed clear through and I had to scrap it (saving the buttons, of course!). Totally learned my lesson!
I would only use an inside, climate-controlled storage facility for things like your Hermes collection. Either that, or the home of a friend!
