* TWO INDIVIDUALS and an organization have received the 1988 Utah Governor's Folk Art Awards, given by the Utah Arts Council.

The Swiss Chorus Edelweiss received the Governor's Cultural Heritage Award. The chorus was formed in 1934 to promote and preserve Swiss culture in Utah, and now includes numerous second- and third-generation Swiss Americans. It has given nearly 500 concerts over the years, including choir singing, yodeling, folk dance and performance on the alpenhorn and other traditional Swiss instruments.

Award recipient Merle Shumway of Provo is a singing instructor and teacher of such old-fashioned dances as the Chicago Glide, the Varsouvienne and Rye Waltz, along with pioneer standards such as the waltz and schottische. Shumway grew up in Mormon communities in northern Arizona and plays an extensive repertory of pioneer tunes on piano and guitar.

Sandra Jenkins received the Service to Folk Art award for her 10 years of helping Hmong refugees from Southeast Asia. With her husband, she is co-founder of the Hmong Heritage Foundation, which helps Utah's Hmong residents market their beautifully crafted embroidery work. The Jenkins have given dozens of lectures and other presentations about these tribespeople from Laos, with the goal of helping them achieve self-sufficiency without abandoning their traditional ways.
