Start the first design from the 7th dot in the row with 13 dots. This will be the centre of the dot grid.
Another photo showing the progress of the pumpkin like pattern sometimes also called the parangikkai or parangipazham ( parangi is Tamil for foreign )
Now we can see that the first pattern has been completed
The next pattern on the left start in the same row of dots and from the 3rd dot from the left end . This will ensure that the patterns just touch each other on one side
The patterns touching at a point on the side
Similarly on the right side , start from the 3rd dot from the end and the image shows the patterns touching each other
Draw the patterns , i.e the two designs on the bottom. Again choose the location of the centre so that the patterns will touch on the side and on the top. The finger is pointing to the dot . This will be in row with 9 dots. It will be the 3rd dot from the end.
Similarly the designs on the top are also created by connecting the dots
