Margaret own a antique store that Margaret owned an antique store that specialised in rare porcelain dolls.

When she opened the business in 1989, it was at a shop in an eastern suburb of Melbourne. In 1999 she started to advertise on the Internet and by 2006 the business had grown to the point where she needed help to keep the business going. After a family discussion one night at the kitchen table in July 2006, it was agreed that Margaret would probably keep the business going for another couple of years and then retire. Emily, her youngest daughter and aged 16, would work in the shop as long as was needed and in return, she would receive any unsold dolls. When Margaret retired at the end of 2009, she decided that she would give the unsold stock to charity and they could auction it and keep the proceeds.
