These elegant modular stars, designed by Ekaterina Lukasheva, are very easy to fold and assemble.
The instructions can be found in the book Kusudama Origami, by Ekaterina Lukasheva.
I used 5 and 6 modules for the stars in the picture above, but they can also be assembled with 7 modules. I folded each module with a 3" x 6" (75mm x 150 mm) rectangle of patterned origami paper.
This bottle is a very nice model, particularly if you fold it from a translucent paper, that I haven't seen posted in origami blogs or pictures around the web for a while.
The bottle was designed by David Brill. The instructions are available in the book Origami for the Connoisseur, by Kunihiko Kasahara and Toshie Takahama.
I folded the bottle with a 6" (150 mm) square of cellophane paper. It is a little challenging to work with cellophane. Reversing a crease is difficult, and it wrinkles easily, as you can see in the picture.
The cap is a traditional masu box. Instead of using the size of the paper recommended in the book, I used a 3"square of origami paper, and adjusted the bottom of the box to fit the size of the bottleneck, to get a deeper cap.
Inside the box I put three traditional lilies, each one folded with a 1 ½" (38mm) square of foil paper.
