From sketch to shirt: how I illustrate botanical t-shirt designs

People ask me sometimes why a flower shirt takes weeks instead of days. This is the honest answer: because I draw the whole thing by hand before it ever becomes a shirt.

It starts with pencil

Every botanical illustration I put on a t-shirt starts as loose pencil sketches, usually dozens of them. I’m not trying to get it right the first time. I’m trying to find the one shape, out of a page of attempts, that actually feels like the flower.

Flowers are deceptively hard to draw well. The petals follow a pattern, but no two blooms line up exactly the same way, and if you draw them too perfectly the design goes flat and lifeless. I’m chasing that in-between space, structured enough to read clearly, loose enough to feel alive.

Line work is where the design gets honest

Once a sketch earns its place, I move into digital line work. This is where I can push proportions and test scale without redrawing everything by hand each time, but the drawing itself still has to hold up.

Single-color line illustration, like the peony t-shirt, is the least forgiving version of this. There’s no shading to hide behind. Every line has to earn its place, or the design turns to noise up close and loses all its detail from a few feet away. Getting that balance right is most of the work.

Bolder compositions, like the gerbera daisy t-shirt, give me more room to play with color and shape, but the same rule applies. If a line isn’t doing something for the design, it comes out.

Color has to survive fabric

Color is always the last decision, never the first. A palette that looks right on a screen doesn’t always look right on cotton. Fabric absorbs light differently than a monitor, and colors that read as bright and clean digitally can turn muddy once they’re printed.

I test a handful of palettes on the actual design before I commit. Some versions lean too pastel and lose the energy I wanted. Others go too saturated and start to feel aggressive instead of warm. I’m looking for the version that still feels like the flower after it’s been through a wash cycle a dozen times.

Designing for a body that moves

A print on paper only has to work once, sitting still. A t-shirt design has to work at every size, on every body, in motion, from across a room and up close. I size each illustration so the detail holds at arm’s length but doesn’t collapse into noise once it’s on someone and they’re not standing still for you.

That’s the real difference between illustration and merch design. The drawing is only half the job. The other half is knowing how it survives being worn.

See where it ends up

If you want to see what this process actually produces, the hand-drawn flower t-shirt collection has the full lineup, gerbera daisy, peony, and whatever I’ve drawn since. Each one started exactly the way I described here, with a pencil and a flower I couldn’t stop drawing.
