Try this. Raise your enlarger head to the height it needs to be to make a 16x20, then print an image (one you think looks really good at 11x14) on four sheets of 8x10 paper. Process, dry, and put together to make a sorta-16x20. Do you like it more or less than the 11x14?
This is a great tip! Thanks seadrive... It's moments like these that make me love APUG more and more
