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.
Step 3: Glueing
Step 4: Tourniqueting
I used some rope and a pair of screwdrivers to tighten the sticks together.
Now you can let the glue dry.
Step 5: The ear
Mine is approx. 20cm x 8cm.
I did all the sanding with an angle grinder.
When the glue of the mug has dried ,you can also sand this.
Step 6: Decorings
Best is to screw these behind the handle into one piece of wood.
You could also use some rope to put around the mug.
With the angle grinder i made some grooves and glued the rings in.
