Back in 2013, when Sketch (software for designers) was new, I started Sketch Tricks. Where I wrote articles and shared resources to help designers improve their Sketch workflow. As a result, I was asked to write a Sketch tutorial for Net magazine.
In 2015 I sold the domain name to a friend for a small amount, so they could continue working on the project. Before selling Sketch Tricks it had reached 3700+ email subscribers, 5500+ Twitter followers, and 2300+ Medium followers.
