To me, printmaking is more than just an art standard to teach, it is a passion of mine. I have a couple of degrees in it so it feels like a big part of my identity. My yarn stamp lesson was a fun and easy way to introduce the students I love to the medium I love, just like I was introducing two good friends who I knew were going to get along really well.
The following technique is great for young children and students like mine, who have multiple disabilities. Each student picked a shape, letter or symbol to make. They folded a rectangle cardboard in three parts so that the middle part was less than a third and the two sides would bend back and be pinched together to become the handle. We used masking tape to keep them together.
Once the yarn is dried, you just pour tempura or acrylic paint in a shallow plate and begin dipping and stamping.
Think about the whole image. Repetition and rhythm are principles of design. Try out a couple of different colors.
My students are visually impaired, so we did some of our prints on recycled braille paper. For other prints, we added sand while the paint we'd stamped was still wet. The tactile element is so important for my students, but I wish I had used colored glue instead of paint for the stamping. Unfortunately, a lot of the sand fell off after the paint dried.
