Well this is kinda embarrassing, but after putting together a couple of more rows I discovered one of the problems was entirely mine...some of the seams at the ends narrowed making it off...I'm correcting them as I run across a wayward seam. Another reason for leaders and enders but I was chain piecing the 120 blocks so it was just my bad....they have gotten better. Quilting is teaching me lots of lessons..about life and quilting..learning to let go of perfection(to a certain extent) and trying new ways of doing things...
