I was lucky enough to be given a fabulous massive 72 bar box of these little beauties.  Using them for the first time at a life drawing class at English Bridge was rather a challenge but what a pleasure!  I played with various ways of using them (drawing onto pre-wetted paper, spritzing a drawn line, spreading the wet line with a paintbrush, using a paintbrush directly onto the art bar to pick up colour, etc.)…the possibilities seem endless and the colour goes on beautifully and vibrantly.  I ended up with two or 3 ok drawings and extremely messy fingers!
