Matt: It's easy, as long as you stick with the basic directions and don't try to overthink it, you know?

Take the time to set up your work area - it makes things go smoothly while you're working under the gun.
Make sure your Polaroids are completely dry. I have not worked with 59 film, but with 669 film, I follow the procedure of cutting a piece of Contac paper to slightly overlay the back of the Polaroid. It helps keep the mess down. Use a thermometer in your hot water tray to ensure constant temperature of no higher than 160. The emulsion will bubble and separate from the backing within a couple of minutes. Transfer it to the cool water tray. Use your fingers or a light brush to coax it off, whichever feels comfortable. The nasty-looking gel substance can be rubbed away and is harmless, as I'm sure you know. Just get rid of it.
I like to slip a thin piece of Mylar in the cooling bath to catch the loose emulsion membrane. Once captured, it is on the Mylar I do my actual manipulation and get it however I want it to look. If you use this method, remember it will flip backwards onto the final receptor paper, so make sure your image or any letters are backwards to you on the Mylar. You might prefer to slip your receptor paper into the cooling bath and catch the emulsion directly. Either way works fine. Have 2 thumbs ready to capture the emulsion; don't let it escape or it can wad into an impossible mass of goo. I cook my receptor paper (generally a 140# hot or cold-pressed watercolor like Arches) in hot water for 30 seconds or so, then gently squeegee it off so it's ready to slap the Mylar onto, and use a brayer to roll the off the image, starting in the center and going outward. Too much pressure will flatten your emulsion in a way you might not like, so be gentle.
Practice makes perfect! Have fun, it's basically simple and you'll come up with your own methods. I use Daylab slide printer and can use any 35mm slide, which is a cool kind of freedom. I don't have the base for the 4x5 film yet, so all my images are on 669 film - but Christmas IS coming.
You can also do image transfers with the 59 film; a different process and a completely different look. I love 'em both. Have fun, and post your stuff here!
