Sorry guys, it never entered my head. A pattern as an image doesn't exist as I installed the brush, made the slight alteration to the cat's right eye, and printed it from within Gimp. Printing direct from whichever program it is installed in means a good printout at whatever size you decide on.
You could download the brush and do the same with any of the many programs that will accept PS brushes, but if you're not familiar with doing that, I'll make a jpg pattern as soon as I get chance.
