Yoshizawa's crab from "Creative origami"

[Elena]

Hi, everybody. I'm a new folder from Bulgaria. The last model I've tried to fold is Yoshizawa's crab from "Creative origami".But I need some help or video explanation for 12- 13 step. I "can't make this pullig out the B part" and the final result is not with 8 legs at 18 step. I can send a scaned .jpg from the book if you are ready to help me...please, be my saver!

Thanks in advance:
Elena

I see the step. Yeah, step 12 isn't very clear. Let me fold to that point, and I will try to post up some photos today!

And if you aren't getting 8 legs at the end, and you can't pull out that part...

Let me ask you this: In step one, are you starting with a piece of paper that has all 4 corners folded to the center? In step one, the diagram shows this already done, and I think if you don't do it, you wont be able to do step 12, and you will get fewer legs in step 18.

I think I'm doing right until 12 step. It's only the pulling part I'm doing wrong. I think I'm not doing the correct thing at 12, because I can't easily pull the B corner...I hope you can upload some photos soon, 10x in advance

I could use an explanation of these steps as well if Anyone is ever put together an explanation.

Also, I have taken some photos of the steps I have done so far in case I have not executed the steps correctly.
