An exhibition by husband and wife artists Darvin and Martha Yoder of Parnell, Iowa, opens Aug. 26 in the Grace Albrecht Gallery of Bluffton University's Sauder Visual Arts Center.

Darvin Yoder, an art teacher at Iowa Mennonite School in Kalona for 32 years, is presenting "Art You Can Touch," an interactive collection of pedestal- and wall-mounted sculpture.

Documenting Martha Yoder's "Images From Revelation" are augmented maps, plus wall pieces composed of woven and printed Bible pages. "I used world maps to indicate that the church is global," explains Yoder, also associate pastor of Parnell's West Union Mennonite Church since 2008. "Weaving maps juxtaposes unlikely places, and it makes us think of disparate parts of the church as important and necessary for the whole."

Bluffton's Lion and Lamb Peace Arts Center, which is celebrating its 25th year on campus in 2011-12, is co-sponsoring the exhibit, which is free and open to the public through Sept. 23. Gallery hours are 9 a.m. to 5 p.m. weekdays and 1-5 p.m. Saturdays and Sundays.
