reall
I can't seem to find good pics of medieval woodcuts or old manuscripts with rings in them
) not surprised! probably cuz there is not much? at least i don't remember seeing it?)
maybe to check here http://www.britishmuseum.org/research/collection_online/search.aspx?searchText=ring&view=list
first decide position and perspecitve!^^ then see what could fit?^^
or google *ring pattern or circle instead of ring?XD ) or just leave it for last?) and do what you prefer now!^^/that's what I did it!^^ in my case with people cards!XD )
but with your *demanding style I don't think you'll have *easy cards!XD XP lolz ))
EDIT just to add someones collection on pintrest!^^)
