If it isn't quilted you can change it easily at this point. You don't have to take out a whole row, just the two blocks and a little of the seams to the blocks next to them. You will always be unhappy knowing it is there. When a quilt is a simpler looking design it is easier to find an error. It is so pretty and well worth your effort to correct the error. If it were an ugly quilt, I wouldn't bother, but this is so pretty.
