The group have been on the run since Saturday night when they managed to escape from prison in Kawkareik Township in the southern state of Karen.
"The police managed to arrest one on the night of the escape, but the other six inmates are still free," Kyi Lin, head of the Karen state police, told AFP.
"They used their longyi as ropes to escape from the prison by climbing over the roof."
A longyi is a type of traditional cylindrical printed cloth, normally cotton, worn wrapped around the waist and then tied into a knot.
They are worn by both men and women in Myanmar, though the women's designs tend to be more tightly fitted and to have floral designs.
