These origami hexagons also make great decorations. You can hang them up or make a paper garland with them. Other ideas include using them as fancy placemats (you can lacquer them or cover them with contact paper) or making small ones to use as pretty origami earrings or pendants. Origami letter folds are traditionally used as a way to send a letter without using an envelope. The note is written on one side of the paper, and it’s folded up into a pretty shape. You can find a few origami letter folds over at Paper Kawaii, and quite a diverse collection of them over at Origami Resource Center. For this hexagonal letter fold, you will need to start with rectangular paper. You can use A4 or US letter size paper.
