My sewing room is 10x12 feet so similar in size. I have re-arranged the layout and functions many times. I have 3 tables in a U shape plus the ironing table which is a 24x 48 work bench. I cut plywood to size and covered with the silver cloth. I want extra room for the iron and starch. Easy to put a cutting mat over it if needed. Normally, the cutting mat is on the 30x60 table.
Good luck with the decisions!
