Bought some promarkers for quick sketches. I am obsessed with colour but have neither the space nor self control to risk choosing a limited range of colours so just bought a cool grey pack. Marker pens have changed a hell of a lot since I was a filly - they actually work too! I adore the smooth "washes" and layering they achieve - they're like quick - drying watercolours. Gonna' stick with my watercolours for the 'colours' though.
