How to paint a beach canvas

Add white and black to blue paint to make various shades of blue and gray.

I began with white, then added a sky-light blue.

I then added darker grays and blues in the middle. I did this several times until I reached my desired look.

I added white to the sky to make clouds.

I then slathered the whole canvas in clear Mod Podge in order to seal it. This was splattered on and dried clear.
