The wooden hammers are used for smoothing and shaping of the notes.
Remember that the surface between the notes must make a PERFECT BOWL!
Hit first on the areas marked green, then on red and then outside the red
on the borderlines to
make the center rise.
If you have done it the right way, the center will rise up. This note still
needs much hitting on the sides to make it rise properly.
This is almost ready. You can reshape (lift up from the inside)
the note after the cutting and
before burning to get the right form. B is good enough, but F still needs lot of work.
