After much folding - I have two lampshades.
The big yellow one is a sun (obvs!) with the planets stretching away from it (which I didn’t make). This is part of my mildly obsessive solar system theming for the kids’ bedroom.
The other is - just a lampshade.
I didn’t do the design, got it from a book which I’ll leave in the bookshelf at some stage, or else welcome to ping me to borrow it. 200gsm paper. I did the sun first, hand-scoring and folding; for the second one, I got smart and used the laser cutter to do the scoring (thanks @Kuniko for tips).
