Mark,
Good anticipation.
Assuming you will laminate only the head with two pieces of pheart in the middle: The finish size of the head will probably be no more than 5 (long grain) x 3.5 x 3" thick (made up of two full size pieces with a couple of smaller purpleheart (?) enclosing
the handle. In this case the pheart needs to be two pieces about 1.5 (long grain matching the direction of the two outside pieces) x 3.5 across the grain. So, small pieces. The two pheart pieces will need to be the same thickness as the top (enclosed part)
of the handle.
The workshop filled quickly after posting on the website, so it appears you didn't make it in time. If that's the case, I encourage you to add your name to the waitlist. It's quite likely there will be an additional workshop.
Thanks for your interest.
Jim
