1)Slide the smaller ink barrel piece onto the needle.

2)Pinch fingers just below ink barrel piece, position staples as evenly as possible, and apply a small bead of hot glue.

3)As a safety precaution I am required to tell you to put a bead of hot glue on the needle tip to dull it.

4)Cut a thread to the length of your desire(I recommend about 4 feet).

5)Tie the thread to the needle(at least a triple knot; very tight) and cut off the excess.

6)Tie the other end of the thread to the clip's bottom loop.

2)Put grappling hook through key ring, loop around ring, and put through key ring again.

Hmmmm, I think it would be better if you make it more "fishy":
-use a tri-pointed fish hook with glued needles
-use "fat" fishing line to make it more resistent

evilkidjr (author)  rubber man4 years ago
