After this discovery, she began to observe the lack of parks and playground in Tokyo, where she was living at the time, and the negative effect that was having on children. In 1971, she created her first work intended for children, which was later donated to a Tokyo kindergarten designed by Hatsue Yamada. She exhibited her next piece at the National Museum of Modern Art in Kyoto. In the early 1970s, MacAdam's work shifted from being simply fibre art, to interactive spaces as well as a leap from muted colours to a rainbow palette. This timeline corresponds with the birth of her son at the age of 44 and a move in 1988 to her husband Charles’ native Nova Scotia, Canada. In 1979, MacAdam collaborated with Fumiaki Takano, a landscape architect, to create another large-scale playspace for a new national park in Okinawa. She was then commissioned to create a similar for the Hakone Open-Air Museum in Kanagawa. These commissions allowed her to begin her work with nylon. The crocheted playground structures are assembled in sections by a team, and can literally use "tons" of nylon. The research that she undertook on public leisure spaces, mainly focused on Japan, has influenced her perspective on the role of playgrounds and parks in the development of children. Her structures are designed for children to have a space to take risks and explore in a safe environment. The spaces are intended to let children use their imagination. In 1990, MacAdam established a business with her husband, Charles MacAdam, called Interplay Design and Manufacturing. The business operates out of Bridgetown, Nova Scotia where the couple works on commissioned projects. MacAdams's textile playspaces are now installed in various locations worldwide, including projects in Spain, Singapore, Shanghai, New Zealand and Seoul. Medium To create her earlier works, MacAdam used a Japanese-developed material called Vinylon, a durable product but inferior to the nylon she has used in her later works which she crochets and dyes herself at her studio in Bridgetown, Nova Scotia. MacAdam's playscape structures are almost entirely made by hand, with the addition of mechanically knotted elements in some pieces. Each work is original. She has cited the architecture of Antonio Gaudi and Iranian mosques as inspiration for her structural textile work. Exhibitions MacAdam has exhibited textile work in museums and galleries in Asia, North America and Europe. Her exhibitions have been displayed in the
