I watched it and was a little overwhelmed by her living room and wondered what the rest of the house was like. I didn't care for the attitude of her daughter.
The shelving in the garage looked great, but as mentioned, it will get dusty, is not climate controled, etc.
I have watched Hoaders before and those people had junk stacked up high and little trails to walk through all through their house. This lady was different. She didn't have OCD. She just needed a little organization and/or a nice little building out back for a studio.
