This is my first attempt at an instructable, so please don't judge too much. Anyways, it's a puzzle heart made from rosewood and I believe Douglas Fir. I doe not have to be made from these two woods, obviously, but it is best two have two woods that have colors that contrast each other,
Step 1: Wood
First step is two choose your wood. Make sure to get two pieces that are different different color and that are roughly the same width. Then, create a stencil of the figure that joins them together and trace it protruded on one piece and indented on the other so that the pieces will interlock. then trace it onto your pieces of wood.
