Add the warm water. Knead the dough 10-15 minutes, adding additional water a little at a time if your dough seems a bit too dry. Too much water will produce a sticky, unworkable dough.
Spinkle a little extra flour on your working surface. Roll the dough out to about ¼" thickness with a rolling pin.
Use your cookie cutters to start cutting out shapes in the dough.
Gently transfer dough shapes to a greased baking sheet.
Use the straw to poke holes into the top of each ornament.
Bake the ornaments for 2 hours. If your ornaments seem a bit "doughy" yet, you can place them back into the oven to bake for another 30-60 minutes.
Allow the ornaments to air dry for 2-3 days before decorating them.
Using a paintbrush, decorate the ornaments with glue and glitter or acrylic glitter paint.
Allow paint or glitter to dry.
Cut off a piece of jute twine, loop it through the hole in the ornament and then tie the two ends together to create a "hanger."
Brush on Mod Podge or spray on a clear glaze finish.
Notes
Thicker dough will take more baking in the oven - up to 3-4 hours. Keep that in mind when you're rolling out the dough.
