I sewed in our dining room for years because we never used it for dining. Then a few years ago we enclosed a single car garage and I got about 3/4 of it for my own sewing room (the other 1/4 has a chest freezer and DH's weight machine). I have floor-to-ceiling cabinets and a large table with multiple drawers. Plus I have my own TV with DirectTV and a DVD player. I love my sewing room!
However, a few months ago we had a major water leak in the sewing room and an attached large storage closet. Quite a lot of stuff that was on the floor got wet. Everything not wet got jumbled and piled on or around my sewing table. We'll have to sort and reorganize the storage closet before I can move all the stuff out of my sewing area, so it's just a huge mess in there still.
Soooooo, I'm back to sewing at the dining table.
