No really Adella, as you said, it's just a little time in keeping it even all over. If it's lumpy, try adding a little bit more water (not all at once, add some and then knead it and check the consistency). You can add food coloring to different piles of the clay and then make your shapes.

We made these years ago, used cookie cutters to cut out shapes, then used a toothpick to poke a hole in the top before baking them. After done and painting them, we used string or thin ribbon to hang them on the Christmas tree. After several years down in the basement through cold and warm temps though, they broke apart. So store them upstairs in a box or whatever.
