I didn't know that blotter paper has become difficult to find.  Of
course ink pens are not very popular anymore so there is not much need
for blotters now.

I bought about 500 sheets of standard sized blotter paper about fifteen
years ago and I still have maybe 300 sheets remaining.  It was military
surplus from a base somewhere so it is "Army Green".  Anyone who needs
some is welcome to it for shipping plus a small fee for my time.  I can
cut it into letter sized sheets and stick in a large envelope.
