I've had this in my fridge for a while, quite afraid to use it...silly me. It's SO EZ! It's also expensive and I didn't want to waste it since I had no design in mind to try, but when I saw this leftover fennel frond sitting on my counter, it seemed like just the right thing to try it out on. Silkscreening has never been easier. I remember using time intensive and chemical-ly intensive materials in the past and never wanted to go there again. Follow the directions carefully and it's a piece of cake.
All you do is put your design, which can be printed on a transparency or regular piece of paper ("developing" times vary depending on which you use) on top of the film, sandwich it between plexiglass, and stand in the sun. If you can find some. Soak the film for 10 minutes in water and that's it. Ready to use.
