Tartan printing At Ochiltree Primary---- The P1, P2 and P3 classes were covering a Scottish theme we put together a project for them to print tartan designs. The children were given different thicknesses of plastic which were glued onto small boards. the children then painted the stripes with different colours, then printed the stripes onto the paper. Once this was completed they turned the boards 90 degrees and printed them again. Giving the impression of tartan.
