Sprite Stitch Board!

As I'm moving forward with getting my Etsy shop up and running, I have a question for those of you who sell patterns: What, if any, information do you put with the pattern itself? For example, pre-packaged kits have a ton of information as to how to stitch the pattern, how to take care of it, etc etc, but I'm not sure what I should include.

I include the number of DMC colours in the pattern and an approximate size when stitched on 14, 16 and 18 count aida. I figure that anyone buying patterns off etsy already known what they are doing.
