Divide the leaves into two batches of 7 each to make two rolls
For the first roll, take the biggest leaf of that batch and place it upside down i.e veins side up.
Apply a thin layer of the batter using hands (preferably) and spread it all over the leaf.
Place another leaf upside down again but in alternate way to the first i.e pointed part of the leaf is now at the broad portion of first leaf.
Spread the batter evenly on top of the second leaf as well.
Place the third leaf upside down in the same way as the first i.e the pointed side is at the broader side of second leaf and so on.
Repeat these steps for all the 7 leaves.
Now form tight roll - fold the botton slightly, then bring in the left to tpuch the middle line. apply some batter to help with sticking. Similarly fold the right to touch the middle line. Now roll starting bottom to up rolling as tight as possible.
Similarly make the second roll.
