Designers and creators are always looking for unique patterns to incorporate into projects, making digital pattern creation a lucrative opportunity. Start by designing patterns in vector graphics software like Adobe Illustrator, ensuring they’re high-resolution and seamless. Upload your designs to marketplaces like Creative Market, Etsy, or Spoonflower, where they can be purchased by designers. Niche patterns, such as bohemian, floral, or geometric, often perform well. Consistently creating new patterns and promoting your work on social media can grow your sales over time. This business model can provide passive income as customers repeatedly download your work.
