Grace Lister here on Stitchin Fingers has kindly provided a tutorial on Paper bag printing.

Collect some paper bags with bright clear designs on them. The cheaper kind of paper works best and paper with a shiny surface will not transfer. Lay some baking parchment onto your ironing board, then lay a piece of thin cotton or polyester material on top. Flatten out the paper bag so it is one layer and lay it face (design) side down onto the fabric.

Cover with another layer of baking parchment and iron over this with a fairly hot iron. Press fairly hard and smooth over the layers. Lift one corner to see if the design has transferred. If not, try ironing again perhaps with a slightly hotter temperature.

This technique does not always work as it depends to a certain extent on the dyes or paints used. If it does work well, it is sometimes possible to take a second printing. I have found that provided the material is ironed after printing, it will take washing quite well.

Warning: The material will fade if left in strong sunshine.
