For this task you’ll need almost a zero skill in wood working. Or you can ask to help a friend who’s familiar with such a labor.
The easiest way is to take a square-shaped 10×10 mm wooden rod and make sticks from it. Round-shaped sticks are also an option.
You’ll need 1.2 m of rod for one sticks set. But take 2 m – just in case.
Make the channels a little bit more narrow – 9 mm instead of 10 mm. It will provide strong connection between sticks.
Make sure that rods are made from solid peace of wood. Often shop pieces are made from different pieces and connected with a glue. Such rods are inappropriate
