P.S. I'm going to post a link to this in the module forums because that is useful and pertaining to a particular activity that some may get stuck on.

This is totally awesome. Shame I'm so cack-handed at folding. Thanks so much for helping me with my OU exercise.

Not only is it an equilateral triangle, it is also the largest equilateral triangle you can fold from the square. I credit Tom Hull for this little fact.
Nice Job.

what size square did you use? (15x15, 20x20 ect...ect...) ?
MaryColwell1 1 year ago
@MaryColwell1 Why does it matter? Looking at the pattern of the paper, it must have been a 20cm square.
AdamsSara 1 year ago
Ok, but exáctly what measures do you have to use? That is: which es the precise point along the intermediate creases in which the corners of the paper must land?
snipfer 2 years ago
This is a method that doesn't require measuring. By defining two points, you define a line that - if folded precisely - is exact. This is superior to measuring. Hope this answers your question. [The video explains: Make a crease from one corner of the square, so that the adjacent corner exactly meets the precreased pinch mark. Same goes for the other adjacent corner. Then connect the two corners you created by folding in the two corners.]
