Of course it depends on what one wants to do with the prints. For me I have been making hand made books and using Hahnemuhle 17x22double sided cotton paper which runs just over $10 per sheet but
for 8 1/2 x 11 pages I can at least make 8 per sheet and rationalise that it’s $1 each image. So a box of 25 sheets can make up to 200 pages.
Hahnemule prices don't help with the price of enlarging paper.... Ilford warmtone 20x24" (50 sheets).... $818 USD ......$1200 Cad by the time it gets to me......
