How do you make a calash?

A calash, often referred to as a collapsible carriage or a type of carriage with a folding top, can be made by constructing a sturdy wooden frame to support the body and wheels. The frame should include hinges to allow the top to fold down easily. Next, cover the frame with weather-resistant fabric or leather to provide protection from the elements. Finally, ensure proper assembly of the wheels and axles for smooth mobility.
