I look at the sapling closely before cutting. Look for a straight stave with as few limb entry points as possible. I like 2-3 in in diameter. After cutting try to position the stave as if you were going to string it. See if it twists in your hand.
You want to leave it a good 2-3 inches longer than you normally leave full stave bows to counteract crown on the back.
Now, take a long string clamp to one end and see if it falls on the handle.
You have found the back.
Next draw a marker line down each side to delineate back from belly.
With a hatchet, I remove the belly being careful to not build in a twist. Stay straight on each side. These are too small to split effectively.
Take off the bark.
You can actually begin to floor tiller getting the limbs to bend an inch or 2. It will dry faster.
Let it dry and make a bow. There a re buildalongs on my site.
