Rhian Griffiths will face Lorraine Winstanley on Sunday afternoon at the inaugural PDC Women's World Matchplay as the sixth seed and speaking ahead of the tournament, she didn't expect to qualify so is going to take in the whole experience.
"I never thought I would even make the top 20 so to make the top eight is just brilliant," she told
BBC Sport Wales.
"It will be the biggest match of my career, up there with competing at the Lakeside at the World Championships."
"Hopefully I'll do well, it's going to be so special to be at the iconic Winter Gardens in Blackpool. I just want to make sure I play well and don't make a fool of myself," she said.
"It's massive that it's the first [televised, all-female tournament] but hopefully it's not going to be the last and there's more tournaments to come.
"To get to the Grand Slam - someone would have to pinch me."
It is the end of a road from local league to the big stage for the 41-year-old and she believes it is living proof of what can be achieved.
"I played in local league, then it went to super league, county and then I was chosen to play for Wales, which was such a honour," she added.
"It just proves that anything is possible, I never thought I'd be doing anything with darts like this."
She will also look to emulate her compatriots, Gerwyn Price and Jonny Clayton with the former set to be in the men's final on Sunday evening.
"What Price and Clayton have achieved is brilliant," she concluded.
"Wales is such a small country so to produce the calibre of players we've got is just amazing."
"The top eight now will hopefully show we can play darts and be as entertaining as the men."
"Darts is a sport which you can play from aged eight to 80, so I hope more exposure and tournaments will encourage more women to pick up their darts."
