My husband built on a 12x24 room for my sewing space and said you will never fill this one up!! Well he finished it in July and I got moved in it in August and its full,LOL
He laughed and said oops,but we didnt have roon to go wider but he said maybe next year he can go longer,I have a longarm in there too so that took up room. But I love it!!! Its better than my little 10x 11 room I was in. But go bigger if you can.PS dont forget a closet!! We did.
