What Am I?

I am white as a cloud in the blue sky
Floating lazily by
I am soft like a feathery thing
Freshly plucked from a bird's wing
I am rough like sand
Rubbing against your hand
I am very mundane
Nothing more than just plain
But I am very useful everyday
Cleaning up messes before they stay
And when you're through in the trash I go
So tell me now, what am I? Do you know?

Remember during our poetry unit when we had that describing game in class? Where we closed our eyes and chose something out of a basket and then had to describe it? So this was my item. Kind of late, but it's still a decent poem. Enjoy!
