Suggestion for your snake/sewing room: set up a shelf system on one wall for the snake cages and another shelf and cabinet setup for the sewing on another wall. Set up your table so that when you're working you can glance up at the snakes and see what they're up to. The most practical way for the snake setup would be to use lightweight cages, accessible from the front that are stackable or go on a rack (not cheap, but your snakes will live with you 20 or so years so the initial investment will be worth it for the long term enjoyment of you and your snake friends).
