I used a pocket-hole jig (Kreg Jig) to attach bottom board to the side boards, so I used the wood screws (6 total) that came with the Kreg Jig. And 6 smaller screws are needed for the handles and bottle opener. You will need at least 8 – #8, 1″ wood screws for assembling the rails. You can make the whole carrying case with the plywood.
You can probably get by with 1/4 or 1/2 sheet of plywood. I used 3/4 inch plywood, but you won’t need a full sheet. Note that the actual measurement of these boards are 1.5″ X 2.5″ but they are called 2 X 3 in the store. I believe these are select pine so they have fewer knots. lumber and you’ll need 4 of those boards for the blocks alone. Your home improvement store should carry 2″ X 3″ X 8 ft. We also added handles and a bottle opener. To make it look nice, my daughter did a little painting and staining. Just cut 48 blocks of wood and build a simple box to hold them. Overall, the giant jenga-like yard game is a fairly easy project. I’m so proud of her and her artistic side and willingness to learn something new. Just to be upfront, my daughter helped me on this project and did 98% of the project.
