Stained glass supplies, how-to books, stained glass classes and repairs since 1969.
Just like Mrs. Grover Cleveland would have bought if her bag were dressmaking instead of riding to hounds. (Or was that Woodrow Wilson's mother?)
No sewing room should be without this original equipment from 1915, but you should also have some on hand for locating things on maps and for vaccinating your dog against Barlow's disease. (Or vaccinating Barlow against your dog's disease, for that matter.)
Sold by the dozen.
