This is how the framework is created
Before you start, you should think about how big you want the lantern to be. The width of 11.5 cm is already given by the wooden sticks.
Once you have decided, cut four pieces of the appropriate length from the square strip. That is, they can be a little shorter so that they don't overlap.
If necessary, sand the wood a little more, then lay the wooden sticks together and move each second one a little. Then glue two pieces of the square strip onto the sticks with a little distance to the edge.
