I'd agree with cirom here. I have been working on a (private) deck of my own for three YEARS now; and am not even half way. It's photo collage, on computer, so going by Golden Moon's remark, I should have been finished ages ago...
Whereas there are also physical painting artists like Chronata and jackdaw* who set themselves deliberate time limits of - I forget Jackdaw*'s just now, but Chronata's Minute deck was exactly that - a minute per card.
It can often take way longer when you can't hold a pen or brush EXACTLY where you wanted it.... And when you get to the levels of complexity of images in Cirom's decks - words fail me.
The principle of "this is not the work of a moment" is one thing for discussion, yes, but to suggest a time frame or any kind of average would be counter-productive, I think.
Interesting to talk about illustrated vs non illustrated pip cards - do some creators do it JUST to save themselves effort ? I know many do it specifically to follow the Marseille tradition, but....
How to choose your medium would be a good topic.
And if you are following a tradition - how do you decide which, and how slavishly (to use the only word I can think of) do you follow it ? Some seem to try to ape Colman's poses precisely; others try to get the meaning ascribed across in whatever way they choose.
And how you choose symbols.
And yes, how to deal with publishers and printers is an interesting issue. What are the perils and advantages of going self-published ? and the sad fact that it is highly unlikely you can give up your day job any time soon
It really ISN'T likely that anyone will land a USG contract and sell millions (not that USG DOES sell
that many, contrary to popular belief !)
And - this does interest me) as you have more and more decks under your belt - do you get faster or slower in the creation process ? Do you find the meanings you use become so ingrained that you can bang cards out fast - as Cirom describes, and I do agree that some do seem to come very fast. (Then again, I will sometimes have a few cards gelling in my head for months and then do them all on one day, having decided exactly what I wanted, so maybe that accounts for part of it.)
Do the cards get worked out precisely in your head before you start one, or do they grow as you create each of them ?
