I recently began a graphic design business on Etsy, partially to improve my skills as a designer, partially to monetize the skills that I have gained, and partially to have fun creating graphics about my interests. 

I sell primarily wall art prints related to sports such as basketball and formula racing, both as physical prints and digital files. I repurpose my designs on other items available through my print-on-demand supplier, such as t-shirts and mugs, to best utilize my effort. 

I have learned a lot since beginning my business, not only within wall art design but also how to start and run an online business that generates passive income after the initial effort.
