Many years ago, when we were first married and before we had children, my husband and I made ornaments from flour and salt for our Christmas tree. The ornaments are still gorgeous years later.
We experimented with the mix of flour, salt and water to use and the ingredients are approximately: 4 cups flour, 1 cup salt and enough water to make a very stiff dough, about 1 1/2 cups water. Form it into a ball and place in the refrigerator for a day.
Press or roll the dough and then cut out shapes with it, using a butter knife. We made churches, apples, Mr. and Mrs. Santa, gingerbread men, and angels.
Make a hole at the top of each ornament big enough to put an ornament holder or thin ribbon through. We used a pencil to make a wide hole.
Let the ornaments dry by putting them on a cookie sheet in an oven on the low setting for an hour and watch them because it could take more or less time for them to dry. After you remove them from the oven you will probably need to let them set and dry further for a few days and even as long as a week, turning them over occasionally.
Buy hobby paints in the colors you want, and I recommend glossy red and white and green, among others.
Testors brand model paints in bottles of gloss enamel work well. Some people decorate with permanent markers which I haven't tried, since we like the glossy paint look.
I painted the year we made them on the back of each ornament.
When Christmas arrives this year, and we get out our heirloom flour ornaments, I will take photos and post them here.
No matter what kind of ornaments you make, your family will enjoy working or playing together while making them, and I'm guessing that for years to come they will be a cherished feature on your trees.
