Making a Custom Photoshop Brush

Today I figured out how to make a Photoshop brush out of a custom picture. I used an old Hoppie picture that I came across in my folder. Here's how:

1) Select the part of the picture you want to use. Dark parts will be more opaque, light parts will be more transparent. Use black to create a completely opaque brush.
2) Go to Edit » Define Brush from Selection...
3) Name the brush and save it.
4) Go to "More Options" in the brush tool.
5) Adjust settings the way you want.
6) Change the size to the way you want.
7) Under the brush selection, go to "Save Brush..."
8) Name the brush, save it, and delete the original brush.
