For this activity, it helps if the items are small. If you find large items, you can feature them on a Nature Table.

Look at what you gathered. If the items have a small hole in them already, that makes them ideal. If they do not, can you figure out a way to tie yarn around them so they don't fall? Or can you figure out a way to put a small hole in the item without damaging it?

Make sure there is a long piece leftover so you can hang it up.

Then hang up the cross from a branch or shelf.

Attach yarn or string to each natural item you want in the mobile. Then tie them to a stick.

As you add items, you'll need to move them out or in on the stick to get the mobile to balance. Keep playing around with your items until the whole mobile is even.
