I have a large house. When we moved in 23 years ago, it seemed huge and half empty. I have built in book shelves in the living room and study. I had them about 1/4 full. My husband said 'Give it a year, you'll fill them". Well, he was wrong, they were full in 6 months. I use 2 bedrooms for my sewing/quilting. I have one for sewing and one for cutting and books and patterns. They are both now full plus the closets. More space = more stuff. lol
