Two small pieces of scrap wood any 1" x  4,6,8,10,12" or plywood, or even old wooden fence wood is perfect.  In fact, the best is a piece of old fence wood or something similar.  One will need to be approximately 6 inches in length, the other approximately 12 inches in length.
There will be downloadable materials posted in the classroom.

There will be a knife carving and possible use of hammer and chisel (only if you have, it is not necessary).  This is done after class, after my how to instructions under your supervision.  If you are not comfortable, then a sketching will be just as good.  Also, there is art done with a stick that needs to be taken in and out of a fire.  If you are not comfortable with this, again a sketch will work perfectly fine.
