I've been making a lot of Fujimoto hexagon flowers from rectangles, and the
first step is always to fold the two top corners in to make the 120 degree
angle. those flaps are not used later, and make the subsequent folding bulky
 at those two points.

I also see Fujimoto (and others) start with a square, then fold corners in
to make hexagons and octagons. There's even a few Palmer models that do it.
If you started with an actual hexagon or octagon, you'd get the same
result; the extra paper adds nothing to the model aside from legitimacy
being from a square. A lot of dollar bill folds do this as well.

I've had this hang up for a while, and have resisted cutting off corners
and bits to remain pure.

I still balk at making cuts to give extra flaps, or to cut a deer shape out
of paper and then fold it in half to make the deer, but I'm encouraged that
just because you *can* do it with a square doesn't necessarily follow that
you *should*.

TLDR: Robert Lang says relax. Thank you!

Thus spake Vishwas Deval vish...@devalgroup.com on 5/6/14 8:31 PM:

... Things
become much easier if this extra paper is cutoff leaving only a small
portion to keep the corner graft in place. Final model is better
looking. There are many such instaces where part of the paper is folded
in and is never used. As I am not a purist about square paper I cut off
this extra paper and fold the model. Question is if I bring such a model
for display at one of Origami exhibitions will it be accepted as true
Origami or get rejected for having cut off extra paper?.

Different origami exhibitions have their own criteria, so you need to
check with the specific exhibition you're considering. For most origami
conventions, pretty much anything goes, but you should say what you did in
its label. For example:

Eupatorus gracilicornis
Designed by Dao Cuong
Folded by Vishwas Deval
From a square with the corner removed

And to be honest are such models really from square paper?

No. It's from a nonregular pentagon (if I understood your description).
There's no harm (and much good) in just saying what you did.

A lot of my tessellations and geometrics are folded from weird shapes
(like, really irregular serrated polygons). I just say what they are. Then
people can decide for themselves if they want to stick their personal
label of origami on them.
