use a bigger leaf for wrapper , leave the cap end longer and keep it in upper case . Wet that portion in your cigar glue with finger and thumb if necessary. Once you are to the head end , keep rolling the stick and hold the "extra" leaf material in the off hand's first finger and thumb. As Juan Carlos said dig your nail tips into the head end a little to form the leaf to the head, this is done carefully because if you twist it too hard, you'll rip off what will become the pigtail. Keep going until it starts to twist loosely and evenly ,then a second time and it will naturally twist over itself forming the pig tail . When I do it , I only make 2 twists on the pigtail then tuck the rest back into the twist. snip off the extra with fine tip scissors.
