Hi Arthur, Try finding a roll of "sketch paper" in an art store. Should be dirt cheap. Usually comes in 50 yd. rolls. That is if you have no luck obtaining some from a member. Paper variety is not what it used to be.
Why are there no speaker jacks on a stereo camera?
It is very hard to find this paper or any really good sheet paper.
I have a small notebook i purchased on a recent trip to Paris and love the paper. It takes fountain pen ink very well and asking the paper store near where i live they seem to think it is Onion Skin paper. There is some on ebay but the cost is high.
I haven't bought any for years, and there seem to be no "old fashioned" stationary stores anymore. But there are two possible sources. I saw some on an on-line paper shop for about $25/ream. Also it is used by black power gun enthusiasts so checking those kinds of sites may be another option. It was great material when typing multiple carbon copies!
