Folding it this way and that

You see all these great ideas on Pinterest, like some beautiful lampshades folded from paper. 
I downloaded the folding instructions and tried it out. It's fairly easy but I am not making actual lampshades. It was more about the challenge of getting the folds right. I have tried other origami projects and have always been defeated.

This was fun and I should get a large sheet of paper to make up a proper lampshade.

Note: You need to use a retardant if you want to turn paper into lampshades.
