Lots of time we need things traced, and we just do not have the resources to do that. For example tracing paper, a window, or some other tracing device. Luckily, you have me to provide you with a new tool!
Step 1: Materials
4 Cardboard Strips
Glue or tape
The cardboard strips have to be
(2) 2 by 4 inches
(2) 2 by 8 inches
Step 2: Arranging the Cardboard Pieces
The cardboard pieces are to be arranged like in the picture below.
The larger pieces (2 by 8) will be arranged in an "L" shape.
While the two smaller pieces (2 by 4)are arranged in a backwards "L" between the two larger pieces.
Now with all of the pieces together, in place, dont glue yet!
Get a hole punch and punch the holes like the picture below.
One on the longer piece, and through both smaller pieces of cardboard.
Step 3: Gluing and Pencils
Now is the easiest step of them all. Just glue all of the pieces together.
What I did was glue where the two pieces met. In the two spots. 1 spot on the bigger 2, and one spot on the smaller 2.
Now insert the pencils where you put the holes in.
Step 4: Usage
Lastly, select an original drawing that you want to trace and set it under the pencil in hole A. (Refer to previous picture not for the points) Place a blank piece of paper under point B. If necessary, secure the pencils to the cardboard and the table with tape.
Use pencil A to trace the drawing and you will see another picture being drawn at pencil B.
Now you can easily trace complex drawings and make copies for your needs. Experiment with the lengths of cardboard, and you wll see that you can easily enlarge or reduce the size of the drawings made.
