 The product revolutionized home sewing.The premise of graded sewing patterns reportedly came from Mrs. Butterick's frustration with contemporary sewing patterns offered in only one size (frequently a different size for each pattern).Unless the intended wearer happened to match the size of the pattern, this necessitated manual resizing of the pieces (using paper, or directly on the fabric with wax chalk) before sewing could commence - a laborious and frustrating process.
