A Round Robin quilt is made by a group of quilters.  To start, the group sets some basic "rules", such as a theme and the size of the center block.

When the quilter finishes their center block, it passes to the "next" quilter in the group.  Usually this occurs during a short meeting where everyone passes the center block they worked on to the next quilter on the list.  That quilter adds the first border or row around the center block, following the theme picked by the group.  Then the next quilter adds the second.  This usually continues until there are three or four borders or rows that have been sewn by different quilters.

The quilter who made the center block then gets the quilt top back to keep and finish.  Sometimes the group meets together and works on their assigned border, and other groups keep it a "secret" until the top is finished and returned to the owner.

Some quilts used a center square and built borders around it, yet others use a "row block" design where quilters in the group follow the theme of the first row by adding rows to compliment.
