Check out these simple ornaments! They are so easy to make and you can incorporate all sorts of therapeutic techniques while making them. Start with Crayola Air Dry Clay. Take out as much as you think you'll need and have the child use both hands to squeeze the clay and roll it into a large round ball. (This is a great sensory experience and also works on hand strength!) Then use a rolling pin or smooth drinking cup to roll the clay out to about 1/4-inch thickness. (Working on bilateral skills!)
Then use your favorite cookie cutters to cut the clay into different forms/designs. If the child's manipulation skills are pretty good, they can even form the clay into their own preferred shape or design. Be sure to use the tip of a pen or paperclip to poke a hole in the top of the ornament for the hooks! Now allow the ornaments to dry for 24 hours.
Now all you have left to do is paint them! You can put them on an easel to work on wrist extension during painting. You can make them as fancy or simple as you'd like. We kept ours pretty basic...with just the date, but they turned out pretty cute!
