Mono printing is a really easy technique. Here are a few of the many experiments I've done lately. The flowers are now FME and quilted waiting for binding.
I used a piece of waxed freezer paper taped to a table. Lightly spread on a background color and then stamped into it. Lay a piece of material over it roll it with a rolling pin or brayer, pull off and let dry!!!! I heat set mine. Interesting technique!!!
