We made these with our younger elementary group (which happens to be mostly girls).
They filled the boxes they decorated with plastic gemstones, bead necklaces, and plastic rings. They loved it!
I thought this verse was perfect for this lesson:
"Braiding your hair doesn’t make you beautiful. Wearing gold jewelry or fine clothes doesn’t make you beautiful. Instead, your beauty comes from inside you. It is the beauty of a gentle and quiet spirit. Beauty like that doesn’t fade away. God places great value on it." 1 Peter 3:3-4
