A Wolverhampton couple who have invented a revolutionary craft tool are showcasing it at a major exhibition in the US.

Husband and wife Peter and Josie Low set up Coppernob Card Craft - named after a nickname for auburn-haired managing director Josie - at their Wednesfield home two years ago.

They designed and are now marketing the Multiscore & Fold (M & F) Scoreboard - a portable white plastic moulded board that enables card and scrapbook makers to score lines onto card.

The product taps into a growing interest in homemade greeting cards, presentation boxes, envelopes and frames.

The board won the bronze medal in the craft category at the British Invention Show in 2004.

Coppernob is now developing its overseas business with UK Trade & Investment who have supported the firm to attend the 2006 Craft and Hobby Association Show.

The event, held in New Jersey attracts 8,000 visitors from across the globe.

Mrs Low said: "This is an opportunity for us to reach the largest market in the world.

More than 10,000 buyers, including the major US chain stores, together with retailers, distributors and individual buyers, will be there.

"A year ago, we would never have dreamed of doing this."
