I have been learning how to make boxes from 3mm thick board and covering them. Here is my first attempt. The box measures approx 22cm x 16cm and is covered with a strong material called Skivertex which resembles leather/snakeskin/crocodile skin. The next one I make will I think be gessoed, painted and embellised. Watch this space.......though it could take some time as we have sold our house in France and are moving to the UK mid March. Exciting times!
