Etching Tools


Step 1

Step 1

  • Fold one sheet of computer paper in half (hamburger)

  • Fold it again (hot dog)

  • Open it up- you should have folds that cross in the exact center of your paper


Step 2

Step 2

  • Use a compass to draw a LARGE circle

    • To do this, place the gold brad in the center of the paper where it folds. Place a pencil in one of the holes near the edge of the paper. Draw a circle that fills the page. Use the hole that is one hole past the 4” radius mark.


Step 3

Step 3

  • Fold the paper again the way you did before (hamburger then hotdog) Make sure y our circle lines up evenly!!!

  • Then fold the paper in half again, this time from the center- dividing your circle into 8 even sections

  • Open up the paper


Step 4

Step 4

  • Your paper should have a circle that has been divided by folds into 8 even sections.

  • Outline 1/8th (or one section) of your circle with ink pen CAREFULLY


Step 5

Step 5

  • Lay a second piece of computer paper on top of the first.

  • Trace the 1/8th Section onto the second paper


Step 6

Step 6

  • Set the paper with the circle aside

  • CAREFULLY cut out the 1/8th wedge

  • CAREFULLY and PRECISELY fold the 1/8th wedge in half from tip to top (it must be EXACT)

  • Open it again to see the fold


Step 7

Step 7

  • Draw a design on ½ of the triangle in pencil

    **Note: you need to plan to shade/decorate your design with hatching and crosshatching. Keep this in mind when your make your design!


Step 8

Step 8

  • Fold the design over again so that the drawing is inside the triangle.

  • Hold the drawing up to a window so you can see through the paper and see the design

  • Trace the design with a pen while holding the paper to the window- push hard!


Step 9

Step 9

  • Open the paper.

  • The pencil should have rubbed off onto the other side of the triangle making a symmetrical design

  • Go over the entire design with a thin sharpie


Step 10

Step 10

  • Place the original piece of paper (the one with the circle) on top of the paper with the 1/8th drawing

  • Hold them up to a window

  • Trace the segment 8 times, filling the entire circle with the radial design


Step 11

Step 11

  • Get a piece of scratchboard from the teacher (YOU ONLY GET ONE- BE CAREFUL!)


Step 12

Step 12

  • Lay the computer paper with the completed circle on top of the scratchboard

    • Center it!

  • Use a pen to go over all of the lines- throughout the entire design

    • This will impress (or leave indentations) the design onto the scratch board.


Step 13

Step 13

  • RENT a scratching or etching tool from the teacher

    • RENTING: where the student trades in either a student ID or a shoe for a tool

    • Students MUST return their tools at the end of the class period


Step 14

Step 14

  • Use the scratch tool to scratch out the design

  • Each student MUST use HATCHING and/or CROSSHATCHING to shade and enhance their project


Step 15

Step 15

  • Create a pattern to fill the additional space outside of the circle

  • Emboss it into the scratch board

  • Scratch it out with a tool
