The traditional rangoli with lines called padi kolam in Tamil or geethala muggulu in Telugu is also called kodu kolam . These designs are for those who would like to call them that way.
The first kolam above is explained in a series of images. The patterns are drawn using sets of four lines. I have not added any extensions like flowers , spirals , dots that we usually decorate with after drawing the kodu kolangal.
The next kolam again using the standard square pattern and stars. Above the stars we have some free hand decoration to make it a fusion kolam with lines and patterns
