Use a special paper for alcohol-based markers to prevent the ink from feathering or bleeding through the paper. Just in case, use a sheet of protective paper underneath the paper you are drawing on.
Try drawing slightly overlapping circles in different colours to create different types of shading.
Shade with one colour: apply an even layer of ink to one area, and then add another layer on top to deepen the colour.
Shade with two colours: apply a layer of ink and then apply another colour on top.
Lighten with the colourless blender: use the blender on areas that you-ve already coloured in order to lighten the colour there. If you accidentally colour outside the lines, you can dab these areas with the blender to absorb most of the ink.
Practice shading by using different techniques with Panduro Colour Markers! The alcohol-based markers are perfect for colouring and have double, replaceable tips: a thin tip at one end for details and a wide, angled tip at the other for thicker lines and filling in bigger areas. Here, we have created a colourful, abstract pattern by drawing circles in different colours and varying degrees of intensity. Try as you go and see what kinds of results you can achieve by applying several layers of the same colour, and by applying one colour on top of another.
