it started when i was living in an old emroidering factory warehouse in a small town in mexico. there were a lot of nice big sharp needles everywhere.
so i put the sewing needles (the kind that you would use on an industrial sewing machine) in a pin vice and perforate the page along the lines i want. it takes a LONG time to keep punching through layers and you do have to make a LOT of holes to really perforate the pages enough so that they pop out, but if your the kind of person who doesnt mind taking their time like me...
you can use all different kinds of needles, flat head needles can make the edge more ragged, small round ones can give you a nice, tight, fluffy kind of edge. and you can get it to some really tight little corners and spirals.
this is a scene from 'Jericho', a little play of mine. its very tiny , but you can kind of see the fluffy edge made by the pin
and watch out for blisters!
