My partner gave me some lovely paper samples leftover from her place of work - they are huge sheets, 520 x 780 mm and I've been folding & tearing them to make folios & signatures for my bookbinding projects. So I've got some nice folios sized 190 x 130 and smaller ones sized 130 x 97 mm, both of which are torn/deckled on all but one edge.
Can some kind person tell me how to make a faux deckle edge on that one clean edge? I've got everything from 175gsm to 300 gsm, so quite thick paper/card.
Ta very muchly in advance,
