This study in Knox County, Tennessee, was done to determine how those attending Extension clothing construction workshops differed from others; which recommended clothing instruction practices were being used; and factors influencing respondents to adopt or reject practices. Forty-five participants and a random sample of 45 nonparticipants were interviewed. Data were analyzed by numbers, percentages, and adoption ratings. Results indicated that the average home demonstration club member in the county in 1967 was about 49, had three family members, reported a gross family income of $7,867, was not employed, had some training in home economics, and had used two information sources on clothing construction during the previous year. Adoption ratings (including overall scores) were higher for participants than for nonparticipants on all 14 practices. Greatest differences (cited in order) were on clean finishing, trimming seams, applying zippers, staystiching, reading labels and hang tags when buying fabrics, using interfacing, and making darts. Factors influencing adoption included employment status, sources of assistance and instruction in clothing construction, and the types of training received. (Authors/ LY)
