Good question, Rick. I should have covered that.
If your outer shell is 3" wider than the inner, while you're hemming, simply fold 1/2" of the outer shell at 6 different spots, spaced evenly along the edge. That will make the two shells the same length in the hem and both shells should come out even at the corners.
