Great video, Andrew! I use my bathroom, kitchen, garage (the two 750W lamps for exposing are out there), and what ever it takes! I am pouring tissues this evening -- have three ready to be hung up!
But then I live alone, so the fact that it might be a day or two before the shower can be used is no big deal... No one complained about removing the 5-foot claw-foot bathtub and setting up a couple of saw-horses and an old desktop! A permanent arrangement eventually.
I pour 12.5"x19" tissues...using 290ml of glop poured 'free-form' onto the Yupo and spread with my fingers. I cut the tissue down to size after sensitizing -- I get enough for six 4x5x, or four 5x7s, or three 4x10x, or two 8x10s...or a mixuture of sizes depending on which negatives I want to play with. Tissues for 11x14 are poured to size.
