The best way to replicate success is by starting a 30-year-old's kitchen-table side hustle that generates $27,800/mo and requires only 2 hours a day.

The Six-Figure Side Hustle series by CNBC Make It features individuals with successful side hustles who share their routines and habits for generating income in addition to their full-time jobs. If you have a story to share, please email us at [email protected].

As a child, Domonique Brown and her father could only find Hallmark greeting cards featuring Black people at a single store in Upland, California.

In April 2020, Brown started her art side hustle DomoINK, which is a Black-centric greeting card business. She wanted to share her art with others, and now her cards are available in Targets across the country. Brown describes the feeling as "strange" when she first started her business, but now she is proud of what she has accomplished.

Her business on Etsy generated enough sales to cover her mortgage payments on her newly purchased house after several months. Later, she received an invitation from Target to design a collection of prints and home décor for Black History Month, which was launched in stores in February 2023. Since then, she has signed additional deals with Sharpie, Walmart, Airbnb, and Disney.

Society6 licenses some of Brown's designs, allowing you to buy items with her art, ranging from socks to credenzas. Her designs primarily feature Black characters and aim to represent the Black experience, as she states.

Last year, DomoINK generated $333,600 in gross profits, which amounts to an average of $27,800 per month, according to CNBC Make It's review of relevant documents. Despite being a part-time venture, her business surpasses her full-time job as a graphic designer, where she earns an annual salary of $90,000.

Brown devotes two hours daily to managing customer relations and producing content for DomoINK, and when inspiration strikes, she creates new work, she says. Her past work experience in real estate and marketing has given her valuable sales skills, she adds.

Brown talks about how art has provided her with relief from schoolwork, unfulfilling jobs, and people who advised her to create more "white art." She discusses the replicability of her business, building confidence to launch a side hustle, and balancing creativity with her day job.

CNBC Make It: Do you think your side hustle is replicable?

If your brand values representation like mine, it's crucial to effectively communicate and network to increase visibility.

Technical skill and years of experience, in addition to education, provide an advantage. My earliest recollections are from preschool, where I was engrossed in drawing portraits. I have always been an artist.

Believing in oneself and not being swayed by naysayers is crucial to success.

What strategies can you employ to gain confidence in your ability to generate income from a particular activity?

If I went to a retailer and they said "No" to my work, it made me reflect on the past. I could hear someone say, "Artists don't have real jobs. You should have gone into healthcare."

I used to have my artwork displayed in my cubicle while working in real estate. Someone questioned me about my artwork, stating that I would be more successful if I created "white art" instead of "Black art." They suggested I paint a portrait of Jerry Seinfeld.

I always thought, "If I ever see him again, I want him to know that my work is just as valuable as any other kind of art."

How do you differentiate yourself as an entrepreneur and artist from your competitors?

Success can be replicated by challenging oneself.

As I gained more brand deals, I discovered the art of pattern design, which I found to be more visually appealing on textiles such as rugs and towels. My marketing background likely influenced this desire to educate myself on the latest trends and stay ahead of the curve.

My family members, including my parents who worked at the post office and had side hustles painting statues, and my grandmother who was a seamstress and still designed and created wedding dresses at 80 years old, inspired me.

What strategies do you employ to balance your full-time job, a side hustle, and personal life?

Initially, I experienced immense pressure to continuously produce content for DomoINK due to uncertainty about its longevity. As a result, I took on numerous projects, sacrificing sleep and noticing a decline in the quality of my work.

I contemplate life in general and strive to utilize my time more efficiently, which entails prioritizing sleep and travel. I refrain from engaging in my side hustle until after completing my 9-to-5 workday.

I strive to create designs that represent the next person, but sometimes I take a break from business mode and create something solely for myself, expressing my emotions without considering marketing strategies.
