I have been teaching myself how to use pastels for about 12 months now - a friend invited me to a pastel workshop last year and this was the first time I had ever used them. They're fantastic! Such pure colours.
Unison are my favourite and although I have a few colours from other makers I don't tend to use them so much. I just treated myself to the 72 set - feeling a lot poorer now!
Portraits are what I have been focussing on but am going to get down to some still life drawing soon.
