The Englishwoman reeled in long-time leader Pornanong Phatlum in a gripping final-round duel at Royal Lytham to win the Women's British Open for her first major title on Sunday.
And after her tied third finish at last year's Open at Kingsbarns she vowed to improve on that - and she most certainly did, finishing with a five-under-par 67 for a 17-under 271 total to become the first English major victor since Karen Stupples in 2004.
"I thought I'd cry", the 22-year-old Hall said.
"When I was nine years old I used to say "this for the British Open" and to have that experience today was just unbelievable".
"I'm glad I finally played well around here, just in time for it to leave", Thomas said.
Hall added: "I was in the final round previous year [at Kingsbarns] and that is definitely going to help me".
Hall had birdies at the third and sixth before her remarkable run without a dropped shot ended at the 13th.
Both players birdied the par-5 15th after Hall's eagle attempt from 15ft caught the edge of the hole and stayed out, but it did not take long for Hall to get her nose in front thanks to another birdie on the next. She joins a list of players who have gone on to dominate in the women's game: Michelle Wie (2005), Anna Nordqvist (2008), Danielle Kang (2011), Lydia Ko (2012), and Georgia Hall (2013).
She said: "I saw so many little girls come out, three or four-year-olds just wanting a picture with me".

The accident was similar to one on Saturday, when a truck laden with tomatoes crashed into a white van and four migrants died. Italian police posted a video showing the damage down to the bridge after the blast, showing a crater in the road.
Hall also carded a 69 today to finish 12-under par for the Championship this evening.
"It was so nice to have that backing and there were so many people behind me that I feel that was the reason I had good shots".
She now sits in a four-way tie for ninth and six shots adrift of Pornanong, who holds a one-shot advantage of England's Georgia Hall.
While first-round leader Minjee Lee and encountered problems down the stretch at a rainy Royal Lytham to give up two-shot leads on Friday, Pornanong played a steady hand and put her pink ball in all the right places - explicitly, out of the many bunkers that define the course.
She won by two shots from Pornanong (70). "I don't believe it has sunk in yet. I played some really good golf and holed a lot of crucial putts".
An official with NBC/Golf Channel said the decision to air the broadcast in this manner was made based on the fact that Hall and Phatlum teed off in the final twosome at 9:30 a.m.
Hall was not at her best on Saturday.
So Yeon Ryu finished third but could have been a contender for the title had it not been for her early failings. Two-over after four holes, she then hit a purple patch with birdies at five out of six holes from the fifth.
This was Hall's first LPGA Your victory, as she closed with a 67 to finish at 17-under par 271, two strokes ahead of Phatlum and two strokes shy of the tournament scoring record set by Karen Stupples in 2004.
