Help, please. I made this wall hanging without directions for finishing once I had the roosters done. Since I usually just follow directions and don't venture out on my own, this was a project. I used two different borders and a cornerstone. I know the coloring is bad, but the background color is a very pale yellow with a tone on tone of tiny squares. The borders are deep purple and a sort of burgundy rust color and cornerstones a yellow print. They were a 2 inch square when cut. My question is do I need to put a border around all of it now and if so what color do you think I should use. I will appreciate all your thoughts. This is my first applique project so please ignore the mistakes. Thanks !!!!!!
