No, telling you what to do would defeat the purpose..
Here is how it works...
Each quilter in the round robin will create their own center block..Any fabric, any technique.
Then it is sent on to the next quilter in line, who adds a border, any technique but keeping in the color scheme and style of the center block.
This continues until everyone in the round robin has added a border to each quilt.
The last person sends the quilt top back to the person who started it...
So, 5 quilters, 5 quilts... Everyone gets theirs back with all that great imagination and work of all the quilters added on... It is so great....
The rules are usually concerned with quality of fabric and deadlines...
