These rather uncooperative dragons are potato prints. I don't know if you have ever tried it,
but if you are not averse to using potential food as art instead, it's fun. Just take a medium sized potato, and cut away the part you don't want printed with a small knife. The raised surface is painted with acrylic paint and then pressed firmly against the flat surface. In this case, it was fabric. And yes, acrylics can be printed on fabric!
These little fellows were printed years ago on my daughter's tshirt and I am applying them onto a new shirt for her little son.
Just to let you know that I do other stuff as well. Print making is an activity that you can do with kids of all ages. One of my favorite things is printing the backs of leaves or ferns.For that you need a brayer (rubber roller). At any rate, it's fun to find objects to print or use in print making. Ciao for now.
