MS Paint - Shape Decorations

1) First get your image, open a new file, and select a shape, a rectangle, circle anything! You can even get a different shape from the internet.
2) I am using a heart I pixeled.
3) Now I am going to fill this heart with a color that goes with my picture.
4) Now select it, copy it and go to the image you want to paste it on.
5) Go to Image >> Make sure Draw Opaque is NOT checked.
6) Paste it, and move it into the corners of your image.
