I'd love to have an oversized cutting and ironing table. It will have drawers on both long sides, hook areas for hanging rulers on one end, magazine rack/book shelf or more hooks on the other end. And make that on locking rollers so that if I decide to move it, I can. I totally agree with flush mounted tables for the sewing machines. Cabinets or shelving all the way up to the ceiling for fabric stash. Drawers for anything below waist high for yardage and kits. A view of the outside just in case I want to look up while I am sewing.
Skinny drawers somewhere for all this thread I have accumulated. I can't imagine getting to start from scratch on the sewing room. This is terrific for you.
