These are so much fun to make, and they make the house smell wonderful while they are baking. I like the ones made with more cinnamon to make the dough look more like gingerbread. You can buy cheap cinnamon for this.
We have some gingerbread men ornaments made from this salt dough that have lasted for about 20 years. Ours have a clear coat on them & I suspect that is what keeps them lasting so well. You can add white glue to the dough (see comments section) to help them last a long time and to make the dough easier to work with.
Our gingerbread men have raisins for eyes, a thin line of white paint outlining the shape (like icing) and making the mouth & nose. You can use the white paint to add the year on the back or front if you like. Raisins are used again for 3 buttons down the front, but “red hot” cake decorations would look good too. A piece of red yarn is tied around the neck in a bow & looks cute. You can insert a hairpin in the head for the hanger to go through or just glue a hanger on the back of the head. Looks nicer than a hole in the head, IMHO. ;> } Reading the story of the The Gingerbread Man would be a nice touch. This could be a tradition at your house every year. It might get you in the mood to make real gingerbread men to eat too!
