All of the above suggestions are great!
My additional suggestions:
* cutting and sewing directions in a bulleted list, not in paragraph form (easier to check off as I go along)
* If there is anything special, call attention to it...Such as if you need to cut a FQ in a certain way to get all the pieces, make a diagram of that. Or if the pieces need to be cut in a certain order, that would be helpful.
*A text box with helpful hints or fabric selection tips to make the pattern show best would be nice.
*type-written, not hand written directions
*If you do photos for examples, use fabric samples that contrast enough so you can really tell what you're looking at.
*Suggestions for quilting would also be a nice touch
*an email address or contact info if someone has a question about the pattern or a place to check for corrections
*I would like to see ALL new patterns basing yardage on 40" wide rather than 44/45" wide since most fabrics are closer to 40" usable once you trim of the wide selvedges.
