I made one last night. Thanks for the link! Mine turned out a little weird. I must have missed a step since my pages were longer than the cover of the book. I must admit I was multi-tasking (cooking dinner at the same time)... I'll try it again though. What a super cute book! I made an origami bookshelf ages ago. That will be something on my to-do list!
Ah, well I think you have to gauge the proportions somewhat- it took me a few attempts to work out the right proportions. Have you seen the video made by the same person on youtube which is a tutorial for a bookshelf to complement those books? The size is just right for the books to fit on, you can try it! Well, I can never multitask so I'm sure that the model would have been great, considering you can cook and fold simultaneously!
oh yes! it's a really good video in fact, I think `synconi used it for her Origami seminar talk do you like it too? I think all of the ted talks are quite interesting, if only we had time to watch them all!
