I approach my work from a playful experimental starting point. My mantra is
Do something > analyse it look at what you have done > see how it could be done better > then do the thing that could make it better > .
The start of my work with Acrylic, in 2005, was this button. I was experimenting with printing already made up and sewn shirt. I was not that pleased with the shirt but I noticed the button. To me it was incredible. I had never seen anything like it. So I did some research and found out what the button was made of. I went to Swansea Uni and talked to the research boffins there about different sorts of plastics and their thermal properties. I did hundreds of test strips. And then I perfected my technique.
There was a story about a scientist that I related to at this time. She had been doing a lot of experiments. The results were not what she expected. So she dismissed them. A year later someone else won the Nobel Prize for exactly the same results but the had seen them as some thing new.
So mistakes if you look at them in the right way can be the best thing that has happened to you. So wrong they are right. Do not be afraid to fail. You have to have failures to make something new.
