You can create your own designs on your computer, whether it is an actual shape, words, or a combination of both. You print your design onto a transparency sheet and then transfer that to the screen and print your design. Once you get it figured out, it is a fairly easy process.
Another problem I had with the directions came when I was preparing the screen for printing. The machine burns the image you printed onto an emulsion sheet, you then wash off the design and screen print; however, it took me 3 tries to get my design to work. In my first attempt, I did not realize there was a protective plastic sheet on the emulsion sheet that need to be removed. This was my fault because it was written in the instructions, but it was written as more of a side bar tip which I did not read. My second attempt failed, I believe, because the emulsion sheet was not completely dry when I burned my image onto the screen. In reading the online tutorial and tips, I learned that you should run the emulsion sheet through as many drying cycles as necessary until it is completely dry.
This is not a small machine. The packaging size is 31.75" x 21.75" x 10.75" and there wasn't much room to spare around the YUDU screen printer. This is definitely not an inexpensive product (ranging in the $250 - $300 price range). The supplies are not cheap either. The YUDU does come with everything you need to get started and print one design, but you will definitely want to buy emulsion remover or extra screens so you can do more designs.
All that being said, I am so glad I bought this product and look forward to creating many great designs with it. The reason I only gave it a 3 star review instead of 5 was because of the poor directions and also the price. The bottom line though: Yes, it is big... Yes, it is a bit spendy... But it has so many creative possibilities!
