I have just published my first eBook on Ravelry.
My “Celtic Knot Coasters ebook” Never sure whether I should capitalise the ‘B’ in eBook or not.
It pulls together all my present Celtic Coaster patterns
plus my more recent Triquetra Knot Coaster as a bonus pattern.
And I have even made three sales.
I put a lot of work into the ebook though it is pdf format not epub as that is the only format Ravelry allows. Mind you, when I experimented with saving the patterns as an epub file I found that it does funny things to the pictures so pdf is more satisfactory.
I included print friendly (i.e. no photographs) versions at the end of the book but did a bit of editing of the patterns, mainly language, before it was concluded so I hope I changed everything in step.
