Hi!
I'm getting rather stuck on this guy and I feel as though I am trying to fold a physical impossibility. I'm having difficulties moving from step 26 to 27 in Voyer's Grasshopper

You can find it here: http://dev.origami.com/diagram_load.cfm ... hopper.pdf

I have a piece that looks exactly like the sheet in step, but moving to 27 feels like a physical impossibility without tearing the paper. I have re-traced my steps and cannot figure out what I may have done incorrectly. If anyone has done this one before, or has any thoughts on it I would greatly appreciate it.
Thanks much

From what I can see as long as you have done the open sinks correctly in the previous steps (21) same open sinks as in step (23) the step you are trying to do is simply fold the two flaps up.

I found that when i first tryed these I got confused and folded in and out instead of opening up the model and sinking in and out.

Hope that helps.

kind regards
Steve

Oh! That actually does help... quite a lot! I was taking the path of just folding it on the creases and inwards t'wards the center. I'll look into the sink fold there and see if I can make that work happily (though it looks like a slight pain from my perspective here .

Thankyou! I'll check it out tomorrow and get back to you on if it worked or not

EDIT: Just to get back to you; it worked beautifully, thanks much, hopefully the rest will go well

Hello!

I'm having problems doing the open sinks in the steps 21 and 23. Any tips how to crease the peak before trying to sink it?

Any general video/pictures/other help for a bit trickier open sinks would be helpful!
