Are there any "rules" for greeting cards?

I make greeting cards and was wondering if published, are there any rules or limits to what they can say? Or show?


Thanks


BTW (I mean anything)

no rules
Reply:You must not violate any copyright laws. You can't use verses you have copied from another source like a poem, a book or someone Else's cards. If you are thinking of "adult" cards you may not be restricted in what you print but there are going to be restrictions where then can be sold. If, of course, you are doing only on-line cards you will avoid many of the obstacles.
Reply:You're the publisher and artist only you can limit yourself. Regardless what you publish, you will have to find an outlet (store) that will carry your work. So go for it.
