Papercraft and origami tutorials.
Origami is the craft of folding paper. It’s a great thing to try as you don’t need any expensive materials or special equipment.
All you need is a square of paper (the one I used was 12x12cm) and something to crease the folds with. I use a special tool for creasing, but you can just use the back of your thumbnail.
My two rules: fold neatly, crease firmly. Happy paper folding!
