How to Scale Strange Model?

Three Questions:

1. How would you scale this helmet without breaking the unfold? I know that I can export it as an obj file and delete the top visor part in maya (3d modeling program I use) but I'm quite certain that it would destroy the unfold in the process.


2. How do you fix flaps like these?


3. Would a thicker cardstock paper work better for small details in peps? If so, what weight paper would you recommend?

Thanks a ton guys!

Hey, about 2, there is nothing you can really do but trust me its not that bad as long as you know what kind of fold it is. the surrounding flaps secure it and then it attaches very nicely!
Also about 3, i reccommend about 250 grams since it is what i used. good luck mate!
Hope you succeed!
