On andthenwesetitonfire blog here ,Beth has been showing a monoprinting technique based on a video by Laura Kemshall. I gave it a try and here's a couple of mine. It was a lot of fun. I got too much 'noise' on mine, especially on the first one, which I did on one of those white acrylic cutting boards but I still like how they turned out. I did both of them on multi colored fabrics.
This one has the tracing paper on top which shows the design I used for the one below.
