Course Overview

What this course is designed to develop

Print-on-demand fails for most beginners not because their art is bad but because they design a pretty image instead of a manufacturable, findable, on-brand product. This course teaches the working POD pipeline end to end: picking a niche with provable demand, building correctly specced print files (300 DPI, transparent PNG, sRGB, CMYK posters, safe print areas), adapting one design across apparel, drinkware, and wall art, generating mockups that convert, and writing keyword-driven listings that surface in Redbubble and Etsy search. By the end you will have a small, coherent product line of three designs deployed across at least four product types, each with print-ready files, branded mockups, and optimized listings.
