In addition to this explanation... An Amish quilt, actually made by the Amish could be pieced on a treadle machine (Amish shun electricity) or hand pieced but would definitely be hand quilted.
An Amish Style quilt could be assembled in any way, machine or hand and finished by hand.
Some sects of Mennonite will use electricity so the quilt could be machine pieced and quilted.
