This is a step-by-step guide for beginners of the Sun Mandala with 43 points. This shows the first 11 layers (you can also see all of the steps below condensed into the individual layers here). The idea is to get a feel of how this works and complete additional layers on your own (if you desire, or simply stop whenever you feel it is done). The key step to remember is to follow the previous path and then move counter-clockwise one nail. You can see this step in the general set of instructions with pictures here. As you progress it will become easier and may find you no longer need a guide. You may also notice you're skipping the same number of nails with each layer, which becomes an easier method to find the path at the outer edge. Of course, you can also do this from the beginning. The first layer you're skipping 20 nails, then 19, 18, 17, 16, etc. until you reach the outermost circle.
