Hi There,
That girl did my childrens faces that day too, she was good.
Off the top of my head, i think that girls company was Laughing Stock (http://www.laughingstock.ie). Sorry now i could be wrong but thats the first thing that came into my head when i read this post. However she was saying that day that she was thinking of changing the name to something different, she was talking about her red hair & making the name of the company related to her hair, sorry if im not making sense. Sure you could give this company a ring & see if it is the same person.
Good Luck with party.
