peacock of jun maekawa

Hi! please help me! I tried many times to fold the peacock of jun maekawa (diagram in "genuine origami - 43 mathematically based models") but I get stuck on step 15 to 16 (page 111), it is so frustrating, actually it seems to be very simple! Thank you

I haven't folded this model, but I can see what to do... and I just spent an hour trying to figure out how to explain it.... failing to make it clear. A video won't help, you'll need someone to show you how to do a wrap, color-change from Step 14 (rather than 15) to get to Step 16.

To summarize what I had written, you open the flap in Step 14, and invert the Valley folds for the two outside diamonds on each side into Mountain folds. I think it falls into place when you do that.

Sorry,

Thanks a lot anyway, I won't give up!

Looks like no one else is going to suggest, so:

1. Unfold from Step 15, back to Step 14. (In other words, start with Step 14)
2. Reorient the model and Hold it so that the left side is pointing towards you.
3. Look from the top and partially open the side away from you (used to be the right side). You should be looking at the colored triangle that is pointing towards you. There is a Mountain fold that bisects the triangle. Valley folds on the left and right flaps of the triangle run parallel to the Mountain fold.
4. Let's work on just on flap:
A. Invert the Valley Fold on the right flap, just through the colored part.
B. There is a white square Diamond near the right flap. Invert the Mountain fold that bisects this diamond into a Valley fold. And Turn the bottom edges of the diamond into mountain folds.
5. Repeat on the other flap.
6. Turn the Mountain fold that bisects the Triangle into a Valley Fold.
(All this is complicated and may require 3 hands)
7. Close both flaps on their new Valley folds, and at the same time close the Triangle on the new Valley fold.

If you can keep everything together, then the result will look similar to Step 16. When you figure this out, we have one more step:

1. Reorient the model to match Step 16, with the colored triangle pointing to the Right.
2. There is a triangular flap on top (and underneath).
3. Reverse fold the flap inside. The model should look like Step 16.
4. Turn the model over and repeat.

Play with it a few times (it is not simple), let me know the confusion and I'll try again.

Good Luck,

- Hank Simon

Wonderful! I tried and tried and finally, with your help, I' ve got it! But I think I attempt something a little bit too difficult for my skills, cause I've got stuck again on step 56/59. What shall mean "asymmetrically"? only on one side? I will be very glad if you can help me one more time, maybe with a video (if you can) cause my english is not so good. Thank you anyway Hank Simon!

My video is much worse than your English Smile

I'm impressed that you've made it to 56... sounds like good intermediate skills, and looks like the hardest part is nearly finished. Be sure to post pictures when you complete the model.

As I said, I haven't folded it. I am not clear on Step 55, because that looks like a Mountain fold. I assume that you are able to get the picture shown in Step 56 ?

IN Step 56, it seems like you open the model, from the perspective shown by the eye symbol (I need confirmation that you understand the Eye Symbol ?)

Then in Step 57, you change the Valley fold into a Mountain fold, which allows to to wrap around the bottom of the fan (and lock it into place)

And, Yes, it looks like "Asymmetrically" does mean only on one side, rather than in the middle on both sides....

STEP 58 looks like it may require 3 hands to keep all the flaps in the correct order, while pushing the paper into the inside reverse fold.

STEP 59 looks like there are a couple of flaps to reverse fold....

Let me know how your struggles go.

Sorry, this time it doesn' t work! Maybe you can fold the entire model and see how does it work till that step? I think there could be 2 problems: 1) I made a mistake BEFORE step 56 or 2) I really do not understand this point (as you said it seems the more difficult is done, this step doesn' t seem to require particular skills).
An yes, I understand what eye symbol means.
Thanks a lot

No promises, except that I won't have time to look at it until next weekend.

Lovely! Let me know as you can. In the meantime I won't give up!

I folded this again today. I have both the japanese and english version of this book so I folded it when the first version came out. I didn't remember it being this hard. The main way I got this done was just looking ahead to step 59 and gently going with pre-existing creases and some reverses until it fell into place. That may not be very helpful. I'll try again if you can tell me where you are still struggling.

After step 59 , it was very not difficult except that the model begins to get a little thick. You certainly have to start with thin paper to get down to the feet and head folds.

n help me further. you say you just follow precreases but on which side? both? in the middle or what does asymetrically mean in this case? please give me more details, thanks!

Bad news. I did a fairly bad job of folding the Peacock.

I re-did steps 14 - 16, performing the wrap, so that it worked a little better. I had trouble with Steps 17 -18, but forced Step 20 and appeared to make progress to Step 32 OK.

I did the tessellations from Step 31 - Step 54. I used 15 cm Kami, and the paper was too weak and too small for my first attempt, so Steps 43 - 54 were not sharp creases, ruining the the integrity of the tessellation and the peacock tail.

I opened the model at Steps 56 - 57, closed it back and forced Step 58 and 59 to work ... possibly incorrectly. But it turned out recognizable, although not perfect. I followed the precreases on the closest side and tucked everything just into the closest side.... as I said, I forced it.

My plan is to is to make a few more when I have the time, and then use some nice, multicolored paper. So, my suggestion to you is to go to the end, then try again with a little more effort do get Steps 14 - 16 correct, and then see if you gain new insight when you get to Steps 55 -59.

Sorry,
Hank Simon

Here's my go at the extended version. To be honest Step 56-57 confused me a lot. I'm not sure I got it correct in the end but I just continued with the model. It's not essential to the completion of the model.

I've redone this and am back to step 56. I took two pictures. For temporary I just have them on my gallery http://web.mac.com/burtner/iWeb/Site/Photos.html I don't intend to leave them there. Any suggestions where else?

In the meantime, step 15 is not clear to me from the diagram. My notes are that you almost turn it inside out and you reverse the internal diagonals. Between step 56 and 57 I actually pulled out the colored side and put a colored triangle over the left side with its vertex on the mountain fold on the left. That ended up with a colored triangle inside the white triangle hanging on the right side of 59. It all turned out okay with the reverse fold in 60. I wonder if the diagram is accurate?
