Things You'll Need
Instructions
Print out the 20-sided die pattern from the Puam website.
Carefully cut out the pattern, being sure that you do not accidentally cut off any of the flaps.
Fold the paper away from you on each of the black-fold lines until all of the flaps and sides are neatly creased.
Glue the flap on the 14th face to the underside of the 20th face, taking care to ensure a straight seam where the two meet.
Glue the 15th face to the 5th face. At this point, you will have a completed loop with some loose ends on the sides. Glue each of the remaining flaps to the faces to which they are adjacent, taking extreme care not to crush or misshape the die during the final folds.
