My husband manages a storage facility and the owner allowed me to use a 10 x 20 for my 10' long arm. It wouldn't fit in the small apartment that is furnished with the job. Quickly found that it was not large enough. I then requested to take down the wall between my unit and the 10 x 20 next to it. I now have a 20 x 20 space with a long arm, 2 domestic machines, storage cabinets and a large cutting/pressing table. My husband jokes that before next summer I'll want the one next to that. Lol. I am still sewing window treatments and related jobs for income, but getting more and more quilting jobs. They are way more fun than interior decor sewing.
