It's basically just a table-top pool table that uses golf balls. It's actually quite fun and makes for a nice, quiet, drinking game. Plus, it stores as easily as a card table.
Step 1: Gather Materials
3 - 2 inch x 2 inch squareboards -- Mine were 10 foot long, but you really need two 8 footers and two 3 footers for the bumpers.
2 - sheets hobby foam -- the rubbery stuff. It's like 50 cents / sheet.
1 - can spray adhesive -- yes, you'll likely use the whole can and get quite a headache in the process
2 - yards netting -- I used nylon but whatever works. This will be the pockets.
9 - yards green felt -- you must use green or I will beat you until candy falls out.
Step 2: Cut the foam
Step 3: Cut the door
Similar process for the side pockets. Remember that you're building this on a cheap interior door, so the corner pockets will be quite easy to cut because it's hollow EXCEPT where the handles would go. (i.e. side pockets) So remember that the side pockets will be harder to cut.
