Is the top slate? Hubby brought home an old science table for me to use in my studio many years ago - the top is solid slate and it weighs a ton but I loved it and we have moved it along with us 4 times regardless of the weight...and yes it will be a great cutting table if I ever put down the paint brushes. Enjoy it, it looks perfectly at home in your sewing room!
...andif it is as heavy as mine, your hubby is a keeper!
