Know what you mean, an office supply store clerk looked at me as if I was from another star system when I said I was looking for onion skin paper and had no idea what typewriter ribbon was (I know I was mean to ask for that but it was fun). I still have a manual and an electric typewriter, but NO ribbon, booh hoo.

What I hate is filling out questionnaires/forms by hand instead of a typewriter, my handwriting is so atrocious that in 5th grade a teacher suggested that I should study medicine, since I already had the handwriting for it, LOL.

I haven't thought about onionskin paper in years. I don't write many things by hand any more,but I sure loved dipping my fountain pen in the ink jar,filling it up and writing. I used it all through college and then stopped for some reason.

As a crafter person I'm looking into making "archival paper". Paper that will last a long time or forever. They have all kinds of solutions in the stores, that claim to to be archiivl. Time will tell.
While looking into the paper subject, I found out that onion skin paper was used in, among other things, Bibles, and the bibles were still in use today.
