Ink Pen


Computer Paper


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
