Young men and women may volunteer to be a missionary. In LDS funerals, the deceased wears their ceremonial temple clothing to be buried. The first Pioneer Day was celebrated in 1849, with Mormons in Salt Lake City marching in wards, or congregational groups, around Temple Square in a show of patriotism. Many other towns in Utah had their own celebrations. Steven Olson notes that Pioneer Day celebrations reenact an idealized culture, providing a window into Mormon culture. Celebrations in the latter half of the 19th century emphasized how Mormons were a free, blessed, and chosen people. Floats and decorations celebrated agricultural bounties that Mormons saw as God blessing their settlement. Mormon leaders were escorted from their homes to the celebrations, where they participated as speakers. Parades separated participants by age and gender and celebrated traditional gender roles. Dances and sports competitions were common. In Utah where Pioneer Day is an official holiday, the day is celebrated with fireworks and historical reenactments. However, outside of Utah, observance depends on local members; often a congregation will have pioneer-themed talks but no festivities. Dutch Mormons tend not to celebrate it, but in Germany, Pioneer Day is popular among Mormons. In the mid-20th century, several performance art traditions helped revive folk arts. Church-wide folk-dancing festivals taught folk dancing to Mormon youth in the 1970s. Roadshows allowed members to exercise their creative talents on a smaller scale. In some missions, it is common to burn clothing to mark special missionary anniversaries, such as a tie after six months of service and a shirt after one year. Pine furniture, pottery, wool textiles, quilts, woodwork, decorative needlework, and toys have unique Mormon elements. In early Mormon history, pioneers gathered in Utah from Europe and other parts of the world, bringing their knowledge of handicrafts with them. Utah pioneers were isolated and had to make most of their own clothes and linens. They adapted the techniques they knew to the materials they had on hand. Local historian Shirley B. Paxman argues that the pioneers's limited materials combined with their isolation resulted in work that was not self-conscious. Since pioneer women did not think of themselves as artists, their decorative work was for their own or their family's simple pleasure. Pioneer women in Utah made their own yarn, linen thread and silk thread. In the 1870s, pioneer women sold their handicrafts in cooperative stores owned by the Relief Society. When handicrafts were no longer a necessity, they were promoted as improving mental health.
