For making a wood toy you will need a wood board (in this case I used a cheap LOWE'S pine board) but any board will do, even plywood (but not recommended since I intended this as a toy for kids).
Step 1: Tracing and Cutting (Safety First)
As shown in the video, print an image of the basic shape will look like and trace it with tracing paper into the wood and start cutting using all the necessary PPE. Don't know what a PPE is? - Personal protective equipment (PPE) refers to protective clothing, helmets, goggles, or other garments or equipment designed to protect the wearer's body from injury or infection. The hazards addressed by protective equipment include physical, electrical, heat, chemicals, biohazards, and airborne particulate matter.
It is very important to be safe since you cannot grow fingers back.
Step 2: Cutting the Negative and Sanding
With the pieces already cut and adjusting for imperfections in our cuts, sand them and join them so to cut the negative where the pieces will rest. A video is better than pictures so you can see there how I did it. You can make some relief cuts so to help you cutting.
Step 3: Paint and Finish
I used non toxic eatable paint and some Shellac finishing laying the pieces on top of nails so to get all the crevices .
