What's the Sitch?

So let's say I knit something up, say a scarf.  And let's say that I got the idea for said hypothetical scarf from a book of edgings...say Knitting on the Edge.  Supposing I made a slight alteration on said hypothetical edging pattern and used it for aforementioned hypothetical scarf.  Could I post the pattern?

I've checked in the book and it doesn't mention anything.  I've also checked the guidelines for submissions for Knitty.  Books of knitting patterns - edgings, stitches and the like are not necessarily property of owner - I mean can Epstein claim she created mistake rib?  But I'm unsure how to properly attribute this because I don't know if this particular pattern is her own. 

Or am I worrying over nothing?  Just curious.
