During the month of June 1974, she, with the assistance of Marion Denny, crocheted a giant canopy (1500 sq. ft.) using over one mile of tape to provide a shaded area in the courtyard adjoining the British Columbia pavilion at EXPO ’74 [in Spokane, Washington].

Margaret designed her dress for marriage to Prime Minister Pierre Trudeau. The ceremony was held in a Lynn Valley, North Vancouver church.
“The bride was an absolute smash (you should take pride in finding different synonyms for radiant — I have been saving ‘absolute smash’ for a very special wedding) in a Moroccan caftan-style robe she had made herself during a two-week sewing course at Elegance International on Seymour Street in Vancouver.

The yellow centred and white-petalled spring flowers were also featured in the bride's bouquet.”
