I am 13 years old and i was bored one day so i decided to make a marble goal. for this you will need apiece of scrap wood, marker, and some type of cutting source. first draw your plan.

Step 1: Cutting It Out

Now just cut out along those lines but it does not have to be perfect. be careful do not cut your self

Step 2: Making and Cutting the Holes and Sanding

draw a rough sketch of were you want your holes. So now you will need to find a marble and make sure it will fit through the hole once you have cut it out. now grab your sanding paper and round those corners.
