What am I poem

Guess Who I am

I am

Straight and long

You sometimes skid on me.

I am hard

I am made out of wood.

I can be brown green or white.

I can be plain colourful or fancy.

I stay in the dark.

I get wet all the time.

You sometimes slip over me.

I am very tough.

I have lines as straight as string.

I have nails on me.

I am zig zaggy.

I go up and down.
