We have 2 homes - one in eastern WA where we live during the summer and one in CA where we live during the winter. In each location I have a sewing machine, serger and embroidery machine. I also have duplicate supplies in both places like thread, notions, cutting mats and cutters. When I was "stocking" the WA home I went to a lot of garage and estate sales and kept an eye on Craigslist. I got some great deals!
Our CA place is bigger so I do my big sewing there and that's where I keep my sit down FMQ setup.
I do smaller things in WA like doll clothes, garments, small wall quilts that I FMQ on my sewing machine, things like that.
My DH has 2 hobbies - tractors and woodworking. His woodworking shop is in CA, his tractors are in WA so he splits his time between the two.
