Good one, reminds me of the good old subtlepatterns.com (Now at <a href="https://www.toptal.com/designers/subtlepatterns/" rel="nofollow">https://www.toptal.com/designers/subtlepatterns/</a>) from where I picked up background images many times. You have SVG, cool!<p>A great feature will be the ability to preview the website itself with a chosen background. SubtlePatterns.com has this.
