STEP 1
Measure and cut
Measure and cut your cardboard to make two 8 inch strips and two 5 inch strips.
STEP 2
Poke the holes
Measure 1 inch from each side of all the strips and poke a hole at that point with an unbent paperclip. Also poke a hole at the center point (4 inches in) on the two 8 inch strips.
STEP 3
Attach the strips
Join the two 8 inch strips to form a right angle. Run a paperclip through the hole to secure it in place. Add one of the 5 inch strips to the center of each 8 inch strip and secure them with paperclips too.
STEP 4
Add the pencils
Expand the hole in the end of one of the 8 inch strips large enough to hold a mechanical pencil, then tape it into place. Place another pencil through the overlapping holes of the two 5 inch strips.
Add a final paper clip to the other end of the 8 inch strip and tape it to the table. Now you can hold the center pencil and, as you trace it over a picture, the other pencil will draw the image!
WHAT'S NEXT?
Try adjusting the lengths of the strips to see how this affects your drawing. Can you make them bigger? Can you make them smaller?
