FOUR RHYMING RIDDLES

1)

We can number in the thousands,

Yet no two are just alike;

Of different sizes, colors, and shapes,

United together, a picture we create.

2)

Found on a hand and also a tree,

You'll find me on Sunday, occasionally.

3)

A halo of water, a tongue of wood;

Skin of stone, long have I stood.

4)

I'm a sweet-smelling spice,

But, if you alter my first letter,

I'm a hand-warming device.
