Professional Buttonholes are made easy with Smart Marks. Choose Vertical or Horizontal (18 of each are included). Cut the appropriate length of Buttonhole Marks, remove paper backing and position tape at first buttonhole. Select the size of buttonhole comparing the actual button with the marking. You may need to use the next marking depending on thickness of button. Stitch directly through tape to the garment for all required buttonholes using the predetermined markings as a guide. Tear AWAY excess tape. Spray buttonhole or wash with water to remove any remaining tape.
