Pick your own pace and see how your Doodles look!

Moving your hand at different speeds while extruding will result in varied types of lines: moving faster will stretch the plastic as it comes out and form a thinner line - but don't move too fast or you'll pull your Doodled line apart; moving slower will result in a thicker line, but careful, too slow and the Doodle will begin to squiggle up on itself and you'll lose that crisp finish.
