After carefully aligning and pressing the drawing firmly in place, I am coating the entire assembly with a wide strip of clear packing tape. This will help preserve the drawing, as well as keep dust and metal from sticking to the exposed areas of the double stick tape, which could get in the way while I'm working. I find it also helps lubricate the blade when cutting. View Previous Step View Next Step All Work Designed, Executed, and ©1996-2009 by John Lewis Jensen, unless otherwise credited.
