i love small prints, i print mainly 4x5 inch contacts,using carbon, cyano, fibre silver and sometimes a vandyke. i also like to print strips of three 6x45 and 6x6, 6x9cm and sometime a half dozen 35mm.
a fantastic look is to print the same neg in cyano vdb and carbon and frame them altogether.
using small negs is a must for learning carbon transfer as the mistakes do pile up, also another nice thing about small is books, make a nice 12 page book of prints.
i have been making simple 4 ring books using white card and tissue page with a homemade paper mache cover, bound together with stripped and twisted household wire (copper)
anyway im rambling, go small as you cant print more lol
