I'm making a really odd-shaped sticker in photoshop and I would like the edges of the shape to be rounded but it's a weird shape. I made it with the polygon lasso and then just filled the selection with a color.
Is there a better way?
This will work because your shape is fairly easy, more complex shapes might require different means.
You can now group or flatten this with your other.
If you have a Vector Application such as Adobe Illustrator than shapes like this are often easier to create in there. For future reference. Or creating with the pen tool from the start in Photoshop.
