The simple pencil rack shown in the sketch can be easily made from any suitable strip of metal, preferably brass of about No. 15 gauge. Mark off a number of rectangles corresponding to the number of pencil holders desired. With a sharp chisel, cut through the metal on three sides of each rectangle, leaving one of the short sides untouched. The loose laps can then be bent to a shape suited to hold a pencil. The rack can be fastened in place with nails or screws through holes pierced at each end. - Contributed by Mark Gluckman, Jersey City, N. J.
