Put at least 2 electric outlets on each and every wall and put them close to waist high.
Build it bigger.....that is about the size of my room DH built on and it needs another few feet. Put in a electric quilter and took up a lot of room.
Used laminate flooring and I love it! Use a Swiffer cloth on it and takes no time to sweep up the threads and stuff I drop, can see most of the pins I drop, too.
Shelves, bookshelves, drawers for storing your stash is a must!
Enjoy!!
