Choose a ribbon material with a smooth surface
Clean and dry the ribbon before writing
Use a permanent marker, fabric pen, or paint pen
Test the pen on a small hidden section first
Place cardboard or paper under the ribbon to prevent bleed-through
Write slowly and evenly
Let the ink dry completely
Avoid rubbing or folding the ribbon until dry
Use stencils or guides for neat lettering
Seal the writing if needed with a fabric-safe fixative
