The same is true for T-shirt designs; anything amazing starts with only a "concept." You need T-shirt ideas before you can just create a design. Every T-Shirt design begins with an idea, whether you're a brand or an independent businessperson. Any abstract T-shirt ideas or concepts are made explicit through the design. It is imperative to consistently produce new designs and continue honing one's craft if one wants to advance as an illustrator, designer, or artist.
