Wonder if anyone can help me with plaid pant layout. I notice that the grainline of the pant front is not perpendicular to the hemline. Therefore, if I align the grainline with a vertical line in the plaid fabric then the hemline will not align with a horizontal line of the plaid fabric. The back pattern piece, however, is perpendicular to the hemline so its hemline follows the horizontal line of the plaid fabric. Thus, if I keep my grainlines straight and do not alter the lengths then the plaids will not match when I sew the front and back together. Anyone know what I’m talking about or how I should solve the problem?
