I live in a small 2 bedroom apartment with hubby and 3 smallish sons. There is a small (and I mean SMALL) closet in the livingroom that holds all my stuff except the machine. She sits in her rolling trolley thing next to the tv for easy access. Mostly because her trolley doesn't fit in the closet. I have a small bookcase in there to hold even smaller tubs. My stash, if you want to call it that, can fit in 2 large Joann's bags and are in the closet. I tend to buy just over what I need for a project to increase my stash a teensy bit at a time. Someday, when we buy a house, or the kids grow up and move out, I'll have more space.
I can fit a small ironing board, my machine, and my mat on our diningroom table. Problem is, it takes up the whole dang room so anyone that needs to get to the kitchen I have to get up, move the table to let them through, then move it back to sit comfortably. My kids have learned when they need to get through, they have to come in and pick up the iron so it doesn't fall off the table when I move it. I have them trained!
By the size of this thread, you can see how you are definitely NOT the only one.
