Thanks for your encouraging words, WMUTeach and rryder! What's frustrating is the second to last row has also overlapped; the last row is nice and even across the quilt. I am debating on whether to rip out the last half of the offending row at a later time and resew. This is a charm quilt (meaning no 2 fabrics alike in the 1 1/2" 9P's) that I have worked on and off over several years and one of my "special" quilts.
That being said I am off to finish pinning on the next quilt and use a different pantograph!
