Whatever is on hand

Not a new concept.

A simple way to improve your world.

Use what is there,

 even if it is only putting something to use.

Why toss something to the side?

As usual, 

 this is a wandering conversation.

I can see what I plan to create.

Cans of paint

 various shades of blue,

  touch of green

Change a room into an under the sea scene

 Light by the windows,

  Dark in the shadows.

Another ongoing attempt at creativity

 one I will watch slowly,

  while the paint dries.
