Resch triangle pattern
This one is for the keen folders. It's a bit more fiddly to collape into its final shape than the others, but it's certainly fun. For the best result, here it is important that the folds are correctly mountain/valley before trying to collapse the pattern.

Instructions
Everyone has different approaches to folding these types of sheets. Here is my preferred approach:
- fold the parallel lines first, creating an accordeon fold; do this accurately!
- unfold again into flat sheet
- fold or crease (for example with a blunt knife or biro) the diagonal folds individually. Make sure you only fold where the lines are printed, not elsewhere. Don't bother with the difference in mountain/valley folds at this point.
- flatten out, and fold back into accordeon
- start flipping up the folds into the desired mountain/valley arrangement. Start at one end of the accordeon and do the folds row by row. This is the fiddly bit that gets easier with practice...
Happy folding!
