I did a course with Pinstripinguk in March 2008 and got into it more when I got more kit about 3 months ago and loving every minute of it so far... I'm doing a signwriters course in Feb back with Kris and Lynn at Pinstripinguk and I've ordered myself a SataGraph Airbrush. Just practising on anything I can get hold of at the moment and hopefully get to grips with the Airbrush and signwriting over the next few years.
