ABSTRACT:
A device is provided which can be used as an educational means for teaching young children how to tie a double bow knot, particularly in their shoe laces, or as an aid to the handicapped child lacking sufficient manual dexterity in tying such a knot. Basically the device is a planar body member in which is provided two pairs of spaced-apart openings in alignment with one another, the two intermediate openings being connected by a narrow opening or slit. The device allows "bunny ear" loops to be formed in the intermediate spaced-apart openings and to form the double bow knot by making a simple overhand knot with the two "bunny ear" loops.
