This method of making wide wall material is a little difficult, because it requires extra drying and drying, to produce the desired wide material.
The material for this tebok is 10cm wide, using good apus type bamboo.
As for how.
Take the bottom or base of the bamboo, then split it into two parts.
After that, the middle part of the bamboo is peeled and dried in the sun.
After drying, bamboo will expand or contract in the middle.
After that, the bamboo is brushed again at the edges of the wrinkles and dried again,
So that over time the bamboo will flatten.
Repeat until the surface is flat and suitable for bending or in the bay.
Please try.
Hopefully it's useful🙏
