In Adobe illustrator there is a AI implementation where you can generate icons based on text. 
For this pig I used the festure to easily get a icon for this project. 

After getting the right one I made ot simpler in design and created the front piece, mid layer and a backside.

Red = Cut

Green = Engrave

If you like you could add on the backside some messages to the person  its made for. Please mirror for this the backside and then write your text.

Its very easy. Just glue all pieces together like a sandwich. I use mod podge but wood glue micht be better for different material.

I hope you liked this little money gift idea. Have fun using it! ~Anzy
