Arrowheads are chipped out of flint or other points of stone and they are commonly found throughout the United States. These small artifacts are attractive items when they are mounted, but it is important to mount them in a way that does not damage them over time.
Open the shadow box and lay out the backing, which is where you will mount your arrowheads.
Apply a dime-sized dot of white glue to the back of the arrowhead.
Press the glue on the arrowhead to the backing in the position where you want the arrowhead to be.
Repeat Steps 2 and 3 if you want to mount more arrowheads in your shadowbox.
Allow the glue to cure for one hour.
Replace the backing in the shadow box. The arrowheads are light enough that the glue holds them up easily.
