Robert J. Lang - Tree Frog

[J]

Hi,
I need help with the steps 16 to 19...
I've tried to fold this model a couple of times without sucess.
Can "you" help me? With some photo-diagrams, if possible?
Many thanks for your attention!

Well, I don't know if you've figure it out, but anyways...

In step 16 you have to pull the corner diagonally to the right and down. Then let the layer of trapped paper free.
Step 17, close the model using the vertical valley fold indicated in this step.
Steps 18, fold the corner down as indicated in the diagram and squash the tiny layer of paper to the "left".
In step 19 you have to pull out a single layer of paper from inside the paper squashed in the previous step so that the final result is symmetric.

Txs, Carberryi.
I figured out that steps...

Cant quite figure out step 37.
Can anyone offer me some help?

Never mind, a little more patience was all I needed.

I have a question about steps 89 and 90. I'm assuming that in step 89, the mountain/valley folds are incorrect, and that I'm just folding a mountain on each side, and not a reverse fold. If I'm right, then I can't actually do I reverse fold in step 90, because it turns that compact little foot inside out, and it doesn't end up looking like step 91 at all. Anyone know what I might be doing wrong?

[Didée]

How did you come to the assumption that #89 would be just a mountain fold instead of a reverse fold? What I did was inside-reverse both #89 and #90. To avoid the inside-out problem with the foot, the easiest way was to do both reverse folds simultaneously.

[FrumiousBandersnatch]

I assumed 89 would be just a mountain fold because that was the only way to get the back feet to look the way they do in step 90. I've got it now...the second fold to make the knees fixes the inside-out issue.

Can anyone tell me the ratio?

[Growlanator]

ratio for what?

[adrijang]

For the frog.
The size of the frog from a 1x1 paper.

Please

[Growlanator]

I'd have to say I think it's about 0.3 but i could be completely wrong

[Didée]

Overall size depends on sharping/positioning of the legs. I folded the frog from a 33cm (13") square, see my flickr gallery if you like. Overall length (hind toe - front toe) is roughly 12.5-13 cm, for the given position of hind legs. Length of the body is 8 cm.

Guys... I am stuck with step 39 - 40. I can't figure out how to stretch the near point to the side... is the paper lay flat at this point?

[youdneverthink]

Hi, I have been working on this model for a while and have gotten the base pretty well down. I keep mangling the fingers and toes. Maybe my base isn't accurate enough, I don't know. If anybody has any tips regarding these little all important folds I'd be glad to hear them. If will try to locate the exact steps in the sequence I'm messing up, but utill then all input is appreciated.

[kevin89]

Pohchunyee: to stretch the near points you just pull them apart and the middle point/flap unfolds.

As far as laying flat, the top part (that was unfolded) can, but not the part underneath it, if I remember correctly. So no, it does not lay flat.

If it helps, all you're doing is sinking the flap inward.

youdneverthink: make sure your paper is square to start off with, as the smallest bit off makes it look really messy and inaccurate. Other than that, just make sure your folds are accurate and keep trying!!!!

And if you are trying to make it look like the diagrams, remember they're computer generated, so I usually just look at the picture at the beginning. And I noticed Robert Lang didn't give his suction cups on the toes
