I like most of the origami designed by Carmen Sprung and here is another of her designs. This one is called √3 Schachtel (Google gives the translation as box or case). √3 because of the paper ratio which is x:√3x. I think this must be the only time that I use such a ratio!!

In case you are wondering what the value of √3 is, it approximates to 1.732. So if one side of the paper is 3 inches, then the other side would approximately come to 3 * 1.732 = 5.2 inches. If you wish to have one side as 6 inches, then the paper size would be 6 inches by 10.4 inches. For more approximations, check out the instructions where Carmen Sprung has already provided some of the values.

As for the folding, it is not very complicated. The last step might require some effort if you are a beginner origamist. I rather like the shape of the box and the fact that it is folded from a √3 paper ratio adds uniqueness to the piece.

Valentine rings are quite popular during this season and here is one that is pretty easy to make.

The ring is designed by Hiroshi Kumasaka. It is made from a square. In order to make a ring that fits you well, add 2 cms to the circumference of your finger. So if the circumference is 6.5 cms, add 2 to make it 8.5 cms. I converted this approximately to 3.5 inches and that is the size of paper I had used.

With Valentine's Day just round the corner, I found this interesting table card, complete with a little heart at the top. The table card is made from 2 pieces - a base and the heart. It was a little challenging to fold, but I love the result, especially the red card with white heart.

Most origami boxes are modular pieces and to get a box this size, you would need really small modular units, which could turn out to be tedious to make. But this box is just perfect in size!

One thing that I would suggest is that, if you are giving this to someone, it would be better to glue the little pocket that is on the inside of the box. I also glued the join at the top of the box to prevent it from opening up!

The Four Leaves Tato is designed by Christiane Bettens, better known in the origami world as Mélisande.

The paper should be at least a 7 inch square to give a usable tato. The first I had done was using regular copy paper. The tato that I completed was immediately picked up by my daughter to store her jewelry :)

The leaf is made of accordian pleats, the more pleats there are, the better the leaf looks. So take your time and make as many pleats as possible :)

A Tato is a Japanese flat container and Tatogami is one of the oldest form of paper folding. Tatos can hold small flat objects like needles and buttons and postage stamps.

Traditional tatos are easy to make, so instead of making a traditional one, I tried out this butterfly tato, designed by Marcela Brina. Origami paper, coloured differently on both sides, works well to bring out the butterfly shape in the middle.

The instructions are clear, though for a beginner it might present a bit of a challenge initially.

The Decoration Box is from the book 'Modular Origami Polyhedra' and is designed by Lewis Simon. The cube is made from 12 modules. Variations made from half a square and from dollar bills are also found in the book.

Of all the cubes that I have tried in the recent days, this is, by far, my favourite. The alternate dark and light strips add so much beauty to the cube. If the folds are well-creased and accurately done, the final cube is quite firm.
