Need more information please. Do you want to sew something or redo a cabinet?
The cabinet make great desks
Since it opens up and is the perfect height I would make a removable countertop and use it as a portable bar/party side table.
Millie,. Is it the kind that the sewing machine drops down, and you cover it with a flap of wood???
Because of the interior storage, it would make a great crafting space. You may need a piece of wood to cover the sewing machine hole when the cabinet is fully opened up. Good luck!
Het there! You can make a small beverage station out of it. Attach a small cooler to the opening where the sewing machine used to be. Then either refresh the finish on the wood or paint it the color of your choice. Use it as an occasional table when its closed and you're not using it as a beverage station. Good luck!
