While free hand rangolis are popular in many parts of India, rangoli with dots called (pulli ) kolam in Tamil is popular in Tamil Nadu. This can be further classified into two types ner pulli kolam and idukku pulli kolam.
To explain it further if one draws a ner pulli kolam with a 15 to 1 dot pattern it means that the central row of dots is 15 and the last row has one dot - odd number of dots are placed in descending order i.e 13,11, 9, 7,5,3 and 1 and a convenient distance (1 cm approx) on either side of the central row of 15 dots.
In idukku pulli kolam the first row of dots is placed, the next row of dots is placed below the first row in between the dots of the first row and the third row below the second row at a reasonable distance between the dots of the second row and so on. This is to be done on both sides of the central row.
Some pulli kolam designs I designed for my blog. I will upload as and when it is possible.
The one above is of 9 dot to 1 dot pattern kolam with four "colourful" birds. A simple design. However the video has also been added.
This rangoli below is of the dots 11 to 6 dots (idukku pulli). A floral design with dots. They are the most sought after in rangoli designs. Probably the beauty and colours of flowers attract us so much that we desire to draw them often. It is preferable to upload videos for rangoli with dots, simple rangolis and for at least some of the free hand designs so that the steps involved are shared with viewers. Accordingly I try to include videos for pulli kolams, simple kolams with dots and for some free hand rangolis. It is difficult to decide how many videos in a post is too many!.
The dot pattern is 15 to 1 (ner pulli)
The video for this kolam, below
The next kolam is of dot pattern 11 to 6 (idukku pulli)
and the video --
The rangoli below is 15 to 1 straight dots (ner pulli). A simple floral petal central design surrounded by some flowers and leaves. I have added a few colours and the the video for this rangoli.
The next rangoli is with 7dots to 7 dot pattern. A simple floral pullikolam design. The video shows to steps involved in drawing this rangoli.
The next rangoli is one that I have already drawn in November 2012 for Karthigai Deepam. I have repeated with a video showing the method. It is very simple and we can decide the number of dots because the pattern is repetitive. I have adopted 6 dots to 5 pattern. The video below is self explanatory.
