I have been wanting to try mono printing for awhile and decided to add some feathers to a sweatshirt that way. I painted the shape of a feather on wax paper using regular cheap black acrylic paint mixed with a little bit of paint extender, then I quickly drew lines into the feather shape and stamped it onto the sweatshirt. I redid this two more times using the same spot on the wax paper so my feathers would be the same, and then added a few little ones down the sleeve. . I love it and have washed it a few times already with out it coming out. The layer of paint seems to be thin enough to not be stiff on my shirt either.
