Sketch a picture on the surface of the wood block. For your first block, make it something simple.
Carve away the negative areas of the drawing with gouges, always cutting away from yourself. Use a V-gouge for fine lines and a U-gouge for larger spaces. Remember that any area you cut will be white in the final print.
Squeeze a nickel-sized drop of water-based ink on a clean piece of glass. Roll the ink with a rubber roller until its evenly covered with ink.
Roll the ink on the carved wood block, coating the surface evenly. As soon as the ink is applied, place a sheet of paper on top of the ink. Roll the back of the paper with a rolling pin to help transfer the image evenly.
Peel the paper away from the wood block slowly. Your print may not be even on your first try -- it's OK, just re-ink your block and try again.
