Now we had to mount the arrow heads to the arrow. To do this we used a jig saw to rip a notch into the arrow. The arrow heads were not consistent so we had to cut each one to the thickness of the arrow head. We inserted the arrow head and wrapped it with sinew. To wrap the sinew we just did figure eights a few times then wrapped around the shaft. Sinew sticks to itself so we did not put on any glue to make it stay.
