You can attach sheets of tissue to printer paper with tiny bits of glue stick along the top edge. Make sure when you load your printer that you have the tissue side oriented correctly for your printer so that the tissue will get printed, not the carrier paper. Remove the tissue from the carrier paper and pin or glue it to your quilt top with washable school glue.
Or, they make sheets of iron-on inkjet paper that's water soluble. A little expensive for FMQ, but whatever helps you learn is worth it. I just bought some from amazon, but a lot of stores carry it. I would cut away the excess before I laundered the finish quilt - just to keep the wash-water less "starchy" and not have the quilt come out of the laundry "crispy."
