To help blend in the edges I reached for the glue gun and got messy. I adore the effects you can make with a glue gun, highly underrated!
I then covered the middle of the canvas with a very light blue. To give the top and the bottom of the canvas an orientation I gave the top more of a blue hue and the bottom a light brown for the effect of sand/land.
Looking forward to it drying so I can start and attach the beautiful embellishments I have lined up.
