Next image showing showing a step in this chukki rangoli big size 
The distance between the dots decides the size of the dot grid.  So we can adjust depending upon the space available.  If we have more space we can place them far apart. Then around the central pattern draw the connecting the dots as shown in the next four images
Kola podi used by me is that usually available with the vendor, I answer this question in many posts because many readers and viewers have asked this question.  I add rice flour to kola podi and the ratio is for one part rice flour , 3 parts kola podi.
chukki rangoli 21 to 11 , few more pictures for the steps
it is a big chukki rangoli easy to draw
Now connect the dots as shown to form the Tiger's claws patterns.  If formed with curved lines the claws will look naturalistic , if we are comfortable with straight lines also we can draw so

Try this periya kolam with dots for important festivals like Bhogi , Kaanum Pongal also
For my mother it was one of her favourite pedda muggulu 

After forming the six Tiger claws and the patterns at the centre , the remaining dots are connected to form rhombus like shapes to complete the kolam.
Translation or transliteration of puli nagam may be  wagh nakh or huli uguru  or puli goru.  Please let me know the correct name in Kannada and Telugu
White kolam or white muggulu is ready
Add colours to complete the kolam .  Filling colours for this kolam needs at least one hour.  Hence such designs are reserved for festivals like Pongal or Sankranti.  They are rarely drawn for Diwali when we have different kind of rangoli.  
I have tried to add as many images as possible to make the steps easy to learn and practice.         
This is one of the most popular rangoli designs drawn in our family for Pongal kolam or Sankranti muggulu.  Just like they have family songs in movies, this kolam or muggu as my mother used to say is a must for Sankranti festival decoration.  My mother learnt this from her mother and so we can see how old this kolam is .  Probably more than a hundred years old.  My mother used to say that there was a lot of competition as to who used to draw big and beautiful kolam for Sankranti in her place ( Vizianagaram near Vishakapattinam ).  So she and here brother used to spy the houses in their streets and the adjacent streets to see what others were drawing early in the morning.  In fact I understand that it was my grandmother who sent them on that mission , so that she could decide what she wanted to draw for the festival.  She invariably chose this one .  Though it uses a big dot grid 21 dots to 11 dots it is a very simple rangoli design because it uses the basic geometric shapes of rhombus, and straight lines.  It is called Mandrakappa in Telugu because it represents the claws of a scorpion.  The beauty of the kolam depends of the smoothness of the claws or curved lines because all other lines are straight.  This rangoli is suitable  for filling up of colours also as is evident from the picture showing the kolam with colours filled.  While filling colours we have to do it patiently and carefully. 
Mrs. Uma Chandrasekar from Mumbai sent me a mail asking about "Puli nagam " kolam.  I understood it as pulli naagam and serpent drawn with dots for Naga Chaturthi and sent her the link to that kolam .  She clarified that it was "Tiger's claws " that she was referring to. Since I was not aware of a kolam with that name,  I asked my elder sister also living in Mumbai, Ghatkopar and she told me that this muggu Mandrakappa is also called Tiger's claws in Tamil.  
For this kolam muggu , we cannot change the claws  patterns , six of them in the kolam.  We can change the remaining patterns at the centre and other dots .  We can have various combinations of patterns and the result is hundreds of kolam with the same theme.  
These "family kolam " no one knows when they came into existence.  We have no recorded version in the notebook or book.  Just as the Vedas were handed over from generation to generation from scholars to the students only through the audio format.  I understand that they were made to repeat the stanzas again and again the memorise .  Similarly these kolam were probably memorised by seeing the mothers or elders draw the kolam .  Our mother and grandmother drew many very big rangoli with dots for Sankranti or Pongal but we have not recorded them in any note book consequently my sisters and I try to record what we remember and recollect.
