What I have been doing a lot of last week

Last week I signed up for a class on "object drawing" with the intent that this could help me draw voluminous things, I bought some play-doh and started making simple shapes, sticking them on each other and turning them around. Very much in the spirit of the first Preston Blair lesson where you draw on an egg and draw it from different angles.

I drew the simple, general shapes first, imagining the object in 3D, even drawing out the surfaces I didn't see




Also some some volume-feeling hatching


And some other ways
