I didn't know that the design idea orginated with the MSQC, did it? The method, maybe, but think the actual design idea is much older than that. To be honest, if it was me, I'd leave that part off of the quilt itself. For the label, I think the:
Pieced and Quilted by Michael Holmes.
with the year and location added to it.
Maybe tuck the rest in with a small sign to be displayed with the quilt. I know you want to give credit where credit is due, but that would be more label than what I'd want, personally. :)
I wanna see the quilt, btw!! ;)
