I was crap at school... thought of myself as not artistic. I have since discovered I'm not bad. I can definitely copy... and am good at manipulating graphics on a pooter... & then copying the end image by hand onto canvass. I even have one of my paintings on the wall of my lounge.
I have come to the conclusion that the crap materials provided at school don't help inspire you.
*confession* I did my daughters Year 8 & Year 9 art projects for her (I will justify this with - we knew she wasn't going to select art as a GCSE option... with the demands on her time, art was not a priority... though the art teacher failed to see this). Anyway.. she (I) got an A for every project!
(so ner ne ne ner ner to Mrs Glover... MY art teacher who said I had no natural creativity... maybe being made to do the same picture as everyone else - pencil sketching a crumpled coke can and a pair of trainers was the reason for my lack of inspiration!)
