For Day 15 of World Origami Days 2015, I have made a traditional fancy box.
This is a very simple traditional model, and another one that is good to make with children. It takes about five minutes to make, but actually looks like it takes a lot longer!
Any paper will do to make the Fancy Box, and kami is probably the best bet. Paper that is coloured differently on each side will give a nice effect on the decoration, as the picture shows.
Instructions are below. Happy folding!
