My oldest girls just love mermaids. It is the theme of their new bathroom, and they always choose the mermaid or princess images for coloring or drawing. I was working on a mermaid card for my shop, and they decided they needed to make one too.
In order to keep things easy and to help keep track of all the little pieces I precut everything and put all the pieces in ziplock bags. It definitely kept me from having to recut pieces once we started. You can even do this the night before or while the kids are napping (if you're lucky.) This keeps things organized and you from getting too frustrated.
This one is more detailed than some of their other crafts, so we had to work one on one. I had to help with adding the glue to the tiniest pieces, but they were able do the majority of it.
