I think it is just a matter of the terms we all use, but sometimes in different ways.
I "piece" all of my quilts and then longarm quilt them.
You can "piece" each block and then QAYG each block and add.
You can do some of the simple strips quilts (espcially wall quilts and tablerunners/placemats) and do "QAYG" adding each strip. I am sure there are more. I am just familiar with these.
I hope I make sense.
