Bucket of water
Take your right hand and dip it in a bucket of water.
Now shake your hand off and let the water drip off of your fingers.
Practice partner will now place the bow with the frog side on the left and line up the middle finger to the hair and the silver part of the frog.
Place the baby finger to the wood part of the stick, a little on the side, not on top.
Tip the bow vertically with the hand still touching the bow and place the thumb on the backside on the stick in between the middle and ring finger. Voila a bow hold!
