Scalability: Average

Card designing is limited by the time and effort required to create each design, especially if they are custom or handmade. While digital designs can be sold repeatedly, creating a large portfolio takes significant upfront work. Solo operators often find it challenging to scale without automating production or outsourcing tasks, which requires additional resources. Online platforms like Etsy can help reach more customers, but income is still largely tied to the number of designs created and marketed.
