I made it 15cm x 22cm.
It is not so suitible for drinking beer (pallet wood can be toxic) but for decorative purpose or ,like me as a trash and beercaps bin.
If you wanne make one you can drink from ,there are some suggestions in the comments.
Step 1: Cutting the wood
You will need 15 sticks cut at a length of 22 cm and at an angle of 12 degrees.
