Add some seasonal decorations to the present pile this year for a low-cost and eco-friendly stocking filler. These also make great gifts to send by post as they can be disassembled and laid flat.
To make, draw two same-sized triangles on sheets of thin plywood and cut them out using a craft knife or fine saw. Sand the edges smooth. Draw a line down the middle of both triangles and mark the centre.
Cut along the lines, halfway down on one triangle and halfway up the other. Paint the shapes any way you like, then slot them together to create 3-D Christmas trees.
