How to personalize a cotton or canvas bag using Posca markers?
Step 1: Trace your designs on the bag with an HB pencil. Posca markers are available in many different tip sizes, making it easy to vary lines thickness and colour in very large surfaces.
Step 2: Before colouring everything in, slip a piece of cardboard in the bag to stop ink from seeping through to the other side. Another advantage to using Posca markers: their ink is opaque and offers great coverage. White stands out really well on darker coloured fabrics.
Step 3: Continue to colour and draw until the desired result is achieved.
