The Pattern Stamp Tool is something I like to make use of from time to time. You can create your own pattern stamps by drawing a square marquee around a pattern sample then going to Edit>Define Pattern. PSD prompts you to name it – simple.
The fun is selecting different types of brushes to apply it with – but you might find some brushes just can’t be selected – or can they? Yes, hold down Ctrl + Alt (Windows) or Cmd + Opt (Mac) while selecting a brush.
