what are cool creative things i can make with shells, bones, and rocks?

Heyya!!

With the shells you could make necklaces by making holes in them! You can also use shells as a holder for example using big shells for a ashtray, keeping your earrings in, using it to mix paints ect.

You could also make a collage with them!

Also how about sticking shells to old hair bands and grips to make funky hair bands? :)

With the rocks how about painting on them? You could make fun personalized gifts for your friends by painting their names on and drawing them a picture! You could even sell some!

With the bones you could make bracelets and necklaces! Or how about sticking a bone to a paper and drawing in other bones to create a imaginary animal? :)

Hope I helped!
