Digital BW, The Print

Hi Folks, i want to add some 'sloppy borders' (I think that is the 
correct term, I mean a kind of rough medium/large format negative 
edge) to some black and white wedding album prints.  I have no idea 
where I could get hold of such a frame (especially as I have never 
shot medium format....I am using an S2)
Can anyone point me in the right direction (or would be good enough 
to e-mail me a file.....)

Many thanks

Steve
