I was fascinated with vector graphics and SVGs were starting to work consistently across browsers. I read there was a way to add SVG backgrounds that I wasn't using. The deeper I looked, the more I realized there weren't many resources on the subject.
I decided to experiment on my own and ended up building a site similar to my inspiration: transparent textures and subtle patterns.
When I first launched my site, I posted on Product Hunt. It unexpectedly was product #4 of the day and got shared across many web design related websites and groups. At the time my site wasn't even monetized, but since it got a warm reception, I decided to add premium content. After listing on the website, sales started to trickle in slowly. I probably made a few hundred in the first 6 months.
