You came very close to another dream job of mine. I'd love to make signs/business marketing items on paper for a living, but I want to truly create them before doing the printing.
Its mostly just how much we get, we get ALOT of signage, especially during the holidays (I work in a fairly large store). As well as price changes and everything else. And I have to gather together all the paperwork, figure out what goes best where, making sure everything is visible and shop-able, that every product has enough tickets, ect ect. Im told that I will be allowed to pick a helper for December, though. So that will make it easier Im sure : p
I wouldnt mind creating my own signs, like you said, but I dont feel I have the experience to do such a thing. Like I can make a BASIC sign, but like an ad made to catch the attention of the shopper, I have no idea if I could do such a thing, haha.
