A sparkling idea from 6 years old kid
Children often come up with brilliant ideas. For example, I recently bought a sticker book for my child. In this sticker book, you can create your own stickers by yourself by coloring empty stickers. My child, who saw this, brought an envelope and put a sticker with a picture on it to match the theme. And they named it "The Magic Envelope."
This might come in handy when making your own envelopes. In this way, it would be more fun to use a simple sticker book for multiple purposes.
