Preheat the oven to 200 degrees.
Mix the flour with the salt until it's fully incorporated.
Add the water a little bit at a time until the mixture is soft and not crumbly.
Using the kneading hook of a stand mixer or your hands, knead the dough for about 5-10 minutes.
Roll the dough out to the desired thickness. I did mine about 1/4" thick.
Press your child's hand firmly into the dough to get an impression of their hand and cut out around it using the knife.
Use the straw to make a hole in the ornament where the ribbon will be. Note: Don't use my pictures for a reference! I didn't think about the direction the ornaments would hang and did all the holes in the same spot. Learn from my mistakes :)
For the elf, reindeer, and snowmen make the hole towards the top of the middle finger.
For the penguin, make the hole in the bottom of the palm.
Place it on the parchment lined cookie sheet and bake for 1-2 hours.
Let cool completely before painting.
