Leavers shirt

I had people sign mine with pink Sharpies, no problems and they didn’t bleed through onto my skin.
When designing your shirt you could lay it flat with cardboard underneath, do your design, and then let it dry. This will stop the marker from bleeding through onto the other side of the shirt. Acrylic paint also works.

So sharpies are advised? Cos i want to write my name on mine and draw a wreath under. Would that work?

Yes sharpies are completely fine and would work for your idea. Just make sure to have something underneath the shirt you’re drawing/ writing on
