Attach some gauze to the ring. This case I used synthetic gauze used for paper making.
Draw something of your choosing on the gauze.
Tape a window around the drawing. On the back tape wider and extra. This is the side from where the paint will be applied.
Now printing!!
When cleaning the screen ( with water), some of the glue will dissolve but that can always be reapplied.
This way ( by removing and/or reapplying the glue)) it is always possible to adjust your print. This way you can make different images with just one drawing.
