My low-tech approach is as follows: From a string line or two parallel lines, hang two prints back-to-back from two upper corners and also clip the two lower corners together. When dry, but not fully 'crackly', stack the prints back-to-back and face-to-face, and place under a flat board weighted down by some bricks or a cinder block or two. After a couple days, the prints will lie flat, although I realize 'flat' is a relative term in this context. ---Harry. ============================================================================================================= To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there.
