To make the ornament I buy a glass ball for each of the children. Then I paint the palm of their hand white with acrylic paint. I place the ball in their hand and ever so gently they close their hand around the ball. When the white paint dries they use paint pens and sharpies to decorate their fingers to look like snowmen.
I attach the following poem to the ornament. (Of course you change the year. This is from the ornament I made in 2003)
These aren't just five snowmen
As any one can see.
I made them with my hand
Which is a part of me
Now each year when you trim the tree
You'll look back and recall
Christmas of 2003
When my hand was just this small.
