WITH products sold at almost four times the production cost, some interior design final year students of Lee Wai Lee Technical Institute are finally finding out how ''priceless'' their work can be. Organised by 29 final year students, the exhibition aims to provide a platform for the public to appreciate the students' creativity. Organiser Justin Kwok Ka-kui, 20, told Young Post the display also helps introduce the course and its content to the public. ''Through our show, the public can see what interior design students are taught at technical institutes and how we can make use of what we learned to produce furniture which are creative, unique as well as practical,'' said Justin. Thecla Lau King-kei had her reason to feel exhilarated on the day as she had just sold her ''State of Empire Chair'' at $2,800, a price almost four times the original cost of production, which is $750. ''The chair is a combination of two periods of time in Art history. I chose to use the Empire State Building as the back of the chair because it is a creation of one period while the tall back design is the feature of another,'' Thecla said. Thecla, 21, holds a different view on selling her work compared to her classmates who feel sad to part with their creations. ''It's great to have people appreciate my thoughts and effort rather than to keep it at home,'' Thecla said. If you think Danny Chan Shiu-yip's 'Mum don't cook on chair', which is made up of a chopping board, frying pan and four frail-looking spatulas, is a mere display rather than a real chair, you are mistaken. ''It's my second year project and I've been using it as a chair for a year now at home. It is very practical,'' said the 22-year-old Danny. ''The project advocates recycling and reuse of waste materials into new creations and I thought it would be very interesting to make a chair out of my mother's cooking utensils.'' But if you think such a chair is cheap you are wrong again. The production cost is about $200 and the selling price is $1,000 since Danny got new materials rather than ''steal'' his mother's utensils from the kitchen. Elegant, imaginative and modern furniture including chairs, mirrors, cabinets, CD racks, a bench, a cloth stand and a lamp were displayed at the exhibition held in Central.
