You can probably get this lamp made in an afternoon (depending on paint drying time) and it should cost about $15-$20. It uses simple techniques of symmetric and asymmetric pop folds which can be the basis for more complex designs. My goal when designing is to make things with a single sheet of paper that look like they couldn't be made with a single sheet of paper. You can see more of my work at my web site drewpingdesign.com.
Enough gabbing, let's get lamping...
Step 1: Gather Materials
Paper - 24-3/4" x 18" (see Step 4)
Long metal ruler or metal straight edge & ruler
Craft knife with new blade
Something to indent the paper - embosser, blunted nail, empty ballpoint pen, etc.
Tool for pressing folds - bone folder, hard thing, etc.
Double stick tape - 3/4" wide
Puck light with cord, switch & plug
3/4" wood cut to 5-15/16" square
Bumper feet about 1/4" tall
Cord holder clips
Heat shrink tubing or liquid electrical tape
Drill with 1/4" & 3/32" bits
Possibly some other stuff
First we'll build the base...
