My sewing room/office is nothing to show off. I bought a kitchen counter and a file counter with big wide bottom drawer to sit on one end and hubby but rail on other end to mount it. I have plenty of sewing room, but need more storage. My "stash" is in a tote under the counter. My books are in the closet and along the counter, held up with serger usually.
I'm happy we got a great deal on stuff, but I think we could adjust it more, where my sewing machine is flush with the counter. There is a woman on here whon had that done. I use the extension table made from foam that I also saw on this board. It is too far forward so I get a sore back.
The thing I wish I had is room for a big ironing board.
