I don’t know if they are on this site as a member, but I know Oblation in Portland makes their own papers and letterpresses as well. http://www.oblationpapers.com/
I occasionally make my own paper, depending on what I need for a particular project. I usually use my handmade papers for artist books, fine press books or broadsides, but have made some papers on commission as well. I don’t have my own papermaking studio – I rent time at Asheville BookWorks.
I also make paper as well as print and bind. The main floor of my studio is where I do book binding and printing. I have my paper making equipment and silkscreen equipment in the basement where there is a floor drain. I mainly make cotton rag papers from recycling fabric but I also do tamezuki and nagashizuki paper making with asian bark fibres. I do print on my papers as well as make small sculptural pieces.
Porridge Papers makes their own paper – i’ve gotten a letterpressed sample in Uppercase magazine once – the issue dedicated to letterpress. the paper thickness and texture, color (2 sides were different colors) were very impressive – pun intended 🙂
