Woodcuts and Linocuts are some of my favorite processes! I love all the steps and layers in carving a block, rolling the ink, and printing it on paper.
Woodcuts are made by cutting into blocks of wood, with special carving chisels
(a linocut is made the same way, except linoleum to carve into instead of wood). The areas getting carved away do not print, because the ink adheres only to the raised surface of the block.
