Depending on price, I prefer downloads. You get them immediately and don't have to pay postage, but I also expect them to be cheaper because the author doesn't have printing cost or the expense of packaging and trips to post office. I would want the download to be professional looking in style. I bought a cookbook download once and was greatly disappointed by the way it printed. (My 9 year old grandson can type better than it was) It looked like it was typed on word pad.
I like color photos and lots of them, I'm a visual learner.
I would want some patterns using the techniques discussed
If purchased as a printed book, I wouldn't want it to be a photocopy off the Xerox.
I would copy a pattern as I used it.
I would like information on creating my own patterns.
