* Crafting paper
* Scissor (to cut the paper into a rectangular shape)
This is one of my old ibles, I've republished it with better pictures and easy instructions :)
Step 1: Folds
Take a rectangular shaped crafting paper and fold it into half (vertically) just to mark the center line, but you'll have to unfold it to make the next folds.
Now, fold the paper from both sides (vertically) equally, so that the edges meet the center line from both sides (see 3rd picture of this step).
Again fold the paper into half.
Start making small and even folds on the folded paper from any corner.
