First you draw your image, then without unloading the paper, switch out the marker for the blade housing. (you will want to then adjust your speed and pressure) Then press "load paper" which will take you back to the beginning of the page, press repeat last and cut. Voila! I hope that makes sense.
It cuts out everything you drew with the marker so it is nicely outlined. Since I do the Birthday Bulletin Board at my son's school it is so nice not to have to cut a black shadow for everything to give it a nice edge. Not to mention how nicely it highlights all of the 'detail' cuts on shape cartridges.
