I solved the same problem by renting a climate controlled storage unit. It's safe, cameras everywhere, only open during daylight hours, and close to my home. I store all of my fabric and excess patterns there, and routinely make the short drive to pick up/drop off items, cut fabric, make kits, etc. it allows me to keep the design part of the business at home, while the bulky work is done at the storage unit away from pets and distractions!
