I saw this idea mentioned on Pugley Pixel as I was going back through her tutorials. Yes, there's no surprise that I fell down the rabbit hole.

Did I make any of my own stripes? Yes I did!
But how do you make that .png into a pattern you ask? Truly easy. When the .png is opened in PSE, go up to your menu bar, Edit -->Define Pattern, and there you are! Name your little creation. Now go back to or open a blank 12x12. Once again, go to Edit --> Fill Layer
Under Use, select Pattern. Click custom pattern, and look for your pattern. UNCLICK Preserve Transparency or your white 12x12 will remain white. Ask me how I know... Hit ok, and watch your paper fill with your pattern.
There it is! Try it and have fun! Maybe put a a timer on when you start this. Just sayin'.
