In a 1963 Canadian newspaper article about designing children's fashions, we see:
"...Mrs. (Elen) Henderson tries to use only fabrics of pure cotton, silk or wool fibres because she has found synthetic and drip-dry fabrics don't wash and wear as long successfuly...Mrs. Henderson seldom uses fabrics in brilliant colors. Grey, trimmed with white is her favorite for daytime wear. "It makes little girls look sweet and pure. Also vivid shades tend to detract from a child's natural color"...Mrs. Henderson warns motherswho sew not to overmake clothes. "You can kill a garment with too much detail and trim." Most time should be spent on finishing a dress. Clothes with an Elen Henderson label are completely French seamed, usually lined, and hemmed and finished by hand. Mrs. Henderson, designer of the new culotte-styles Girl Guide uniform stresses that children should like the things they have to wear and urges mothers to sew with their children's likes and dislikes in mind."
From a 1965 Canadian newspaper:
"The children's field is becoming such big business that many designers specializing in this area are even becoming well known to the public. Elen Henderson started several years ago with a small clientele of Toronto mothers and now sells to several top department stores in New York. She has also won a string of awards for her originality and custom-looking clothes."
From a 1966 Canadian newspaper:
"Canadian designer Elen Henderson has created several designs for the junior bridesmaid."
From a 1973 Canadian newspaper:
"Shirley Cheatley of Elen Henderson, a Toronto firm that designs and makes girls' clothes, says they are making 400 long dresses in one design which they have never done before. She says she believes adult styles are influencing children's wear, and mentions the caftan as an example. Mrs. Cheatley says style occasionally moves the other way, too, as in the case of the currently fashionable pinafore."
From a 1980 Canadian newspaper:
"Children's wear designer Elen Henderson has won Fashion Canada's woman of the year award...Henderson's career spans 35 years. It started in Leeds, England, where she apprenticed to a custom-milliner for four years before coming to Canada. After her marriage and the birth of her two children, she made children's clothes before starting her own business in 1945. Working in her basement, Henderson produced children's clothes for Eaton's, The Nursery and Holt Renfrew. In 1953 the company expanded and in 1963 Henderson won the Girl Guide "thank you award" for re-designing the guide and Brownie uniforms."
