Magnetic Peg: For practicing tying the knot down to tissue rather than pulling up.  Has 2 strengths for different difficulties.  The magnetic strength is changed by further recessing the magnet into the cap.

To set up, first take off the outer rubber bands and remove the instrument tray.  To weigh down the tying board, you can either rubber band the board to a book, or put something heavy such as a smart phone inside the tray.  Replace the outer rubber bands as they act as grips to prevent sliding of the board while tying.  The different tying task pegs can finger tighten into the openings on the top of the board.  To assemble the cup, first place the 3 “up” panels into 3 sides of the hexagon cutout.  The 3 “down” panels can slot in with the to complete the cup.  Note that there is a slight bevel with the panels so the orientation of the panels does matter.
