I received a query about this origamic architecture pencil holder from a reader who was hoping to find a pattern. The design is by IKO, who used to have a site at http://kamixkaze.xxxxxxxx.jp.
Libros Pop-Up posted a selection of designs from the site earlier this year, and then the kamixkaze site disappeared.
Well, I didn't have the pattern, but I thought I could figure it out. It's not completely, exactly perfect. My stairs are a little different, and I left out the windows. (See improved version, with windows, here.) Pretty close, though!
Print the pattern on the wrong side of the paper. Cut along black lines. Score red lines. Working from the back, push the solid parts toward the front of the pieces. You will end up with folds along all the red lines.
I printed out only the top half of the design on a piece of 8.5" x 11" card stock. Then I cut a complete circle from a 12" square piece of card to back the cut out design.
To assemble, cut and fold the pencil holder (top) part and glue it to the backing circle. Cut along the center line of the bottom semi-circle. Slide one side of the cut piece over the other--the base will be a double layer of card stock. Paperclip (if you want to be able to take it apart and fold it flat) or glue together.
If you don't even know how to start with this kind of pattern, my best suggestion is to get your hands on one of these books.
For online help, try Baud and Bui. Go to Paper Ideas/Origami Architecture. Scroll down to where is says 24 Free Origami Architecture Patterns. Right underneath there is a click point for tricks and tips. There are various pages about cutting, folding and so forth. I suggest trying some of the free patterns to practice making steps and cubes bumped out of cubes (generations).
