A week after Charlotte Savill features in BBC1’s Make it at Market series she is overwhelmed with interest in her swimming-inspired stained glass artwork. Her online shop sold out in 90 minutes, she received £13.5k worth of pre-orders and £12k in commissions. “It’s totally bonkers,” says Charlotte. “All of my pieces are one-offs and every one of them unique, so it is very difficult to make my work in batches. It is a great problem to have but daunting too.”
