in case someone tries.

this model might be a little tricky, because you have to be very precise with the landmarks, as everything must align in step 18. if you are a little off, then the creases will not line up. step 11 seems to be the critical one, and if you are off here (which is easy to be), then you will not be able to proceed far.

instead, do steps 1-10 as diagrammed. then do steps 17-18. use the intersections as landmarks to guide you in doing 11-16 properly.

Thanks so much, bethnor. I've been having problems with this model for months, and I didn't understand why as I am a rather accurate folder.
I'll try this one again as soon as I am back home.
