Well, nothing's ever easy - we know this.....! But in the course of doing all this I am having to: spend several hours sourcing nice envelopes, only to find out that the printers will actually cut the paper so all I have to do is stick it down, learn how to use the pen tool on photoshop (doesn't sound like much, but it's not that easy, especially if you want to know how to make your work visible (!), do a LOT of little diagrams to illustrate the instructions, lay everything out for printing, including the back of the envelope with photo of the item, AND flat drawings.... all this is extra to creating the image for the front of the envelope (which I like doing), and making the pattern pieces. They are OK, so long as you don't have any curves, hahahahaaaaa.....:-(
Maybe I'll just be an artist instead....;-)
Oh well, it'll get there in the end I guess.
