I know it feels wonderful to have that huge hurdle behind you. Congratulations! Enjoy your new lovely location. And I'm sure something will turn up to work for a sewing table. Sometimes you just have to think about things creatively. You might come across a solid door that is being dicarded and you just need to add legs...or lay the door across filing cabinets for a base. Or maybe a stretch of laminated countertop. Lots of options if you are open to them.
