In a mixing bowl, add the water, salt, and flour to combine. Knead with your hands to get it all smooth. Use a rolling pin and roll it out flat.
Have your child press their foot into the dough then use a knife and cut around the edges.
Bake in the oven for 2 hours then let them cool. Once cooled, paint them with brown acrylic paint. Let them dry a bit and put together the antlers with pipe cleaners.
Hot glue the pipe cleaners on the back and the nose. Use black puff paint or sharpie for the mouth and eyes. Make a loop for the ribbon and hot glue that to the back as well.
Finish with a coat of mod podge or a clear coat spray to seal it.
Notes
If the dough is a little sticky add a little flour to get a easy to work with consistency otherwise your child's foot will get stuck and the print isn’t as clear.
