CreativeXpress shares a video regarding the usage of the Yudu personal screen printer. Put the plastic foil over the design you want on your t-shirt and turn on the light on the printer. This will cause the design from the page to be transfered onto the foil. Then you simply place the shirt onto the foil and place a good amount of ink on top of the foil. Use the squeegee to spread the ink over the design and onto the shirt. Let it dry for a bit, then iron the shirt using a cloth or piece of paper between the shirt and iron. Do this for about 3 or 4 minutes and it's ready for the washing machine.
