Instructions
Look for "left handed" written on the boomerang. Most left-handed boomerangs are marked. If the boomerang is not marked, proceed to the next step.
Hold either the dingle or lead arm of the boomerang in your left hand. The dingle and lead arms are the two ends of the boomerang.
Point the V-point, or elbow of the boomerang, toward your body.
Turn the boomerang so the curved side is facing away from you, and the top edge's leading wing is facing toward you. The curved side is often painted. If you can't hold either end of the boomerang with your left hand and still have the curved side of the boomerang facing away from you, it's a right-handed boomerang.
