For some years I’ve been using a symbol for “repeat behind” which has been pointed out to me is non-standard! It’s a fold behind arrow with a dash through it (and optionally, as shown right) which steps to repeat).
I’m not sure where my use of this symbol it came from, but I’d be very interested to know how other diagrammers tackle this thorny issue?
I’m also torn on the fold/unfold. For years I used a line going to the location then returning. more recently, I’ve adopted the single line with solid/hollow arrowheads.
This then leaves the issue of where you fold/unfold and it doesn’t matter which way, such as an initial diagonal. Here, both arrowheads are conventionally solid. Is this wasting a symbol and possibly adding an extra level of confusion? Should I always use “one end hollow”?
I’m losing sleep on this – your thoughts welcomed!
Origami must evolve to go forward. I am in favour of a simple clear symbols.
amen 😉
Robert Lang’s article on diagramming has a discussion of this:

and look for “here we go again: repetitions”. (It’s a great article, generally.)
Though I have to say, personally, my favorite diagrams are Yoshizawa’s – I love the sparseness. Yes, they’re harder to fold from (you really have to pay attention, but then I’ve always enjoyed a puzzle…
Of course, I should have remembered this – thanks Anne. It would be interesting to see how much of it he still stands by 20 years on, but I guess he’s busy enough already 😉
I notice that in your “work wanted” post you use the more normal repeat behind symbol. If it’s clear what you mean, it doesn’t really matter what you use but, you do need to be consistent 🙂
Yes, but that was drawn some ten years ago – I’m forever questioning and developing my own use of symbols and how it can be minimised and clarified. Their use is consistent until it changes 😉
