There are mainly two types of kolam with dots - where are the dots are connected by patterns usually repeated to get a symmetrical design or sikku kolam wherein the lines are drawn around the dots without touching them. 

 In the former type it is a good practice to connect all the dots so that there is symmetry - unilateral or bilateral.  Do not leave any dots.  Use them also to draw some designs that match the remaining part of the kolam.

 If you see in the images shown above some dots remain inside the petals.  However, they match the main pattern and can be left as it is, or we can add some more flour to enhance the dots as shown in the completed design at the top. 

Similarly, there are hundreds of sikku kolangal that have been created and are available on the internet.  If we want to create our own designs we should follow these rules - there should be symmetry, lines should not touch the dots, and no dots should be left unused. Whenever we have time, we should also try to create some of our home, I have tried a few and it is interesting and challenging.
