Your only limitation is your Imagination : )
However, there are a few things we recommend as Dos and Donts they are:
DO USE FELT TIP PENS, CRAYONS, PAINT (if our template), COLOURED PENCILS, COLLAGE, STICKERS.
DO NOT USE FLURO COLOURS, METALLICS, GLITTER OR HOLOGRAPHICS (as they do not print very well).
IMPORTANT: Please note that due to the process of sublimation printing, colours can change and there will be variations from original artworks. Our graphic designers aim to get you the best colours they can, sometimes this involves brightening colours (if supplied artworks are too light), sometimes the process of scanning can dull colours a little. Please note that products with photos we often need to lighten the photo as they tend to print darker.
