I stained a t-shirt and so to make one that was the same I scanned the image on it in order to later print it on a new t-shirt. I opened the scanned image on photoshop and removed the background, then I used the quick selection tool to select the colors (only has 2 colors) and to recolor it as the colors looked dull. The problem is, the quick selection tool didn't make a 'clean/smooth' selection so the edges are VERY bad and I don't know how to fix this! Please help!!
I took a screenshot of the image I'm working on (so that you can have a better idea) and also a close up on the edges (it's like this in all of the image)
