Mix flour, salt and half of the water together in a bowl. Add small amounts of water until dough comes together. Knead a few times until smooth then roll out like cookie dough.
If you find that the dough is too sticky, sprinkle lightly with some flour.
Use cookie cutters to create shapes and transfer shapes to a cookie sheet. To make three-dimensional shapes such as raised eyes or the fish’s side fin, add these pieces before placing in the oven.
Bake for 2 – 2 ½ hours. Remove from oven and allow them to cool completely before painting.
Paint shapes, front and back and let dry. Glue magnet to the back and allow them to dry completely. Decorate shapes or leave plain, depending on the age of your child. Use Sharpie to add fine accents such as eyebrows and smiles. Let dry completely then add a coat of high gloss sealer.
