As we get older, our world gets smaller and we start to doubt and question. We are really suspicious of difference.

In the studio we spend a lot of time working our what materials will work best and also last. We do tests and come back to them years later to see how they are still performing, and this leads our decisions.

In one hundred years time people will look back and think 'these people were really worried about the environment, they were looking at things to do with global warming, and this is why they were making work about these issues'.

I tend to work towards specific exhibitions, so there will often be a big push towards the end when we're finishing off a bunch of stuff.

The studio keeps notes on the details of editions and production processes and the like.

It's interesting to work with what's important today, which is meaningful for our everyday lives.

I pretty much keep everything; we have drawers full of samples and tests and every old catalogue and magazine.
