First buy some "kite paper" from your nearest Waldorf supplier. I got ours from Southern Aurora Books in Bibra Lake. If you're not in Perth, try your local Waldorf supplier, ie Willowwood Cottage or even ebay.
Fold the paper in half (to make this step faster, carefully place 4-6 pages together, making sure they don't slip and cut them all together), cut exactly down the centre, place them all together then fold again lenthways, and cut again. Repeat and cut them widthways, so you will have lots of rectangular coloured pieces of kite paper.
Fold the corners inwards on each piece as shown, then on only one end fold over again, as shown.
Once you have lots of 'uneven' dimond shapes, place a small amount of glue on the spots shown, being careful not to apply too much or your star will stick to whatever surface you're working on.
Place each 'diamond' on top of the other until
you reach the last one, which you will need to slot into place and onto a small amount of glue on the back of the starting diamond.
