Watanabe Dai - A Bird on Hand

[Herc]

Hi guys,

I've tried this model a few times, and only ever got about 30 steps in before the size/type of paper became a problem. I finally have big, quality paper and I've gotten a lot further. But I'm having trouble with a sequence of steps.
It's in Origami Tanteidan 9th Convention. I'm having problems with the sequence of steps 63-67 though, where the arms holding the book and the bird are sunk.

Simplest of all: in step 68, it looks like the book arm is normal width, while the bird arm is half the width, is this just a diagramming error?
Next, when it says open sink, it's the one which leaves that kind of reversible triangular flap, not with the flap tucked in, right?

Anyway, on to the main problem:
I can get exactly the right shape/fold for steps 63-64, without much hassle. But then, in step 65, it shows the head part folded down, which makes seeing what is happening very tricky. I'm really not sure where exactly that bit at the top which I'm supposed to closed sink is. Or how to proceed without affecting the part folded in 63-64.

Is step 66 just showing what the result of this is? Two of the three pleats sunk to half width, leaving the back pleat the original width?

And finally, is step 67 telling me to repeat the process on the other arm?

I've studied the diagrams quite a bit, and it really does look like this sequence is the final hurdle, it'd be a shame for me to force/rush it and make a mess. Any help would be greatly appreciated.

Thanks in advance!

Step 65 is a sort of closed-sink-and-swivel hybrid, if that makes sense. Step 66 is indeed just a finished view, and step 67 does tell you to repeat this step on the layers below. You're right about the error in step 68, just ignore that and everything should be fine.

Okay, thankyou!
Just wanna check though: it doesn't make sense to repeat these steps on the bottom layers of the arm that I've been sinking, since there's three pleats, and the steps are to sink two of them, so there can't be two layers left to continue sinking.
So is the final result that I want to sink two of the three pleats on both arms?
Or just to sink all three layers on both arms?
Cheers!
