If you want to try something new, we’d highly recommend Colin’s Pen & Wash DVD. Colin uses the Pitt Artist’s Pen and combines it with a series of four tonal brush pens. These produce different levels and tones which saved all the cross hatching previously done with just the pen alone.
Once you’ve done the picture you can also colour it using watercolour or watercolour pencils. You could even use pastel pencils. We find this combination works brilliantly and produces stunning results.
