PDF

PDF, but remember this audience is into computers.

My suggestion would be to have a small run of printed patterns (say 50-100) in addition to your PDF downloadable one. You can do this relatively inexpensively at a local copy center if it is all black and white, or has only one page of color. You are correct that the more you do the cheaper it is per copy, especially if it is over 500 copies which would need to be printed. That is the price break point at our shop for whether to do it on the copier or as a printed job. PM me for more info if you wish.

PDF it is fast and easy to download

Definitely PDF! That was I can decide to save it my "Patterns" folder as a "To Do" or print it out myself and get busy on it! :thumbup:

PDF absolutely!

Anyone on this board will probably say PDF, but there are a lot of non computer users who are quillters.

PDF absolutely

I prefer PDF

I prefer PDF because a lot of patterns are free in the PDF format. But you are selling your pattern. When I get a free pattern I like PDF but when I put money out I want a hard copy.
