I just finished my "fish tails" art piece. I was in a mingle entitled "fish tails". We had to have a fish somewhere on the piece of hanging artwork.
This photo isn't the best, but you can see the basics of my piece. I used a 4"x6" canvas and painted it with a glaze medium and paint. I stenciled some random designs on the background using paint. I gave the background some added texture by randomly applying some distress stickles with a paint brush. I added an image of a vintage fish company label and used oil pastels around it for shading. I glazed over the label. It has almost a crackle finish to it. I embellished the piece with an "F" game piece, some netting, small sea shells, and a wire/ribbon/bead hanger.
