To make the lampshade start by folding a piece of paper as shown in the picture
**make sure the vertical lines are mountain fold and the horizontal line is a valley fold
Fold diagonal lines that are also valley folds
You should end up with something like that
Fold 2 more papers the same way
Tape all three papers together
Carefully fold along the creases till you end up with something like this
Punch holes on the outer side of each column
Thread strings through the holes, pull tight and make a knot
place your circuit under the lampshade ...there you go .
REMEMBER TO VOTE IF YOU LIKED THIS INSTRUCTABLE :)
