Manifold - a pad a 100 origami puzzles

I think someone on the BBS mentioned that Manifold was a fun origami puzzle challenge (thank you, whoever you are!). I ordered it on Amazon for $8. It's a pad of 100 square sheets of paper, printed with white and black squares on one side, and nothing (except folding guides) on the other side. The object is to fold each sheet so that all the white squares are on one side, and all the black ones are on the other. I just did two of them, and it was so much fun that I'm saving the rest for a long flight I have coming up.

Here's a PDF you can print out to try five puzzles. Read the rest

The Origami bookmark you can make for free

I can’t tell you how many times over the past five decades I needed a bookmark when none were around. Bookmarks are designed to reside most comfortably between the pages of a book, which makes them awkward to keep in your pocket, wallet, or purse, which is really where you want them when you suddenly need one.

This results in lots of corners being torn off magazines and newspapers to use in a pinch. But the bookmark you get from tearing off a corner is small and often slides either out of the book or down between the pages. And don’t mention folding the corner of the page over – don’t go there. Book publishers (that’s me) don’t like to hear that.

Of course, origami will solve your problem. Before you give up and think, “I can never get those damn paper folds right,” let me soothe your anxiety by explaining that making one of these cute and clever origami bookmarks is easy as pie and takes about a minute.

The Origami Resource Center online teaches oodles of methods for simple square origami bookmarks, or more decorative versions including pandas, penguins, peacocks, and Santas. From that website is a simple square fold that you can make even if you’ve never folded a piece of paper before. I’ve simplified it a bit more, making it (hopefully) even easier.

First, you need a piece of paper, exactly square – anywhere from 4 to 8 inches will do. And I’ll use a piece of origami paper in the photos so it’s easier for you to keep track of which side is which (commonly found origami paper is colored on one side and white on the other). Read the rest
