Have two blocks of 140 Lb rag watercolor paper. 9" x 12" 20 sheets each. Have been in storage for a few years and now are all the edges are stuck together.

Does anyone have suggestions on how to seperate them without distroying them?

Try running the edge of a sharp knife through where the sheets should divide and see if that "snaps" them apart. It's possible, though, if they've become moist and been pressed together that the entire block has become one big physical chunk of paper.

Just the edges seem to be stuck together. So using a knife to seperate them did work with a little fidling around. Thanks for the help.
