My sewing work areas are made from kitchen cabinets that are desk height. I have regular Formica counter tops on them. I have one that is 8 feet long and one that is 12 feet long. Both of them have room for two chairs. Lots of drawers for storage. They are made so they don't have to go against the walls so when I have a big project going I can just let the quilt run over the back edge or I can put a table on the back side for support. I have a cutting table that is two sets of kitchen cabinets at the regular height back to back, creating a 4 foot by 4 foot base then I got a Formica counter top made at 4x6 feet so that I have a hang over edge that I can put a tall chair under to sit while I work if I want. I have plenty of room for all of this as I live alone and have turned the formal living and dining rooms into sewing space. Nice thing about this is that whenever I move, this is the third house I have had these things in, I can just take it apart and move it with me.
