I am looking for high-quality papers for a series of finished pieces in graphite. The pieces will be pretty detailed faces (or apes actually, not people). The paper will need to be able to handle a full range of values. I like a smooth finish so the tones are even. I used to know a lot about papers but it's been 25 years since I really worked with anything other than a sketchbook so I have forgotten everything. I'm looking at roughly 24" x 30" for the pices. Thanks!
