Step five
Pour the bioplastic on a flat surface, preferably something similar to a plexiglass or wax-coated table cloth. As the goal is to create yarn filaments, the wider the flat surface is, the longer the yarns will be with fewer connected points that will weaken the quality of the yarn.
Spread the bioplastic on the flat surface in an even layer, approximately 5 mm thick, depending on the desired thickness of the yarn.
