If the length for the blouse is, 131/2 inches, the length for the back part needs to be 14 inches and 1 inches extra for the front. That is the length for the front part will be 15 inches as it has to be cut and stitched at various points that will lead to reduction in the former length taken.
Take proper measurements. Suppose Length is 13 ½ inches,chest is 36 inches, shoulder is 14 inches, we have the following calculations for it.
Length for the back is 13 ½ inches+ ½ inches = 14 inches.
Length for the front is 13 ½ inches+ 1 inch = 15 inches (the difference in the lengths of the front and back is due to the reason that it has to be cut and stitched at various points that will lead to reduction in the former length taken)
Chest = 36/4 = 9+2 = 11
Shoulder = 14/2 = 7+ ½ = 7 ½
The measurement of waist is not required now but later when the entire pattern is worked out that is, at the time of stitching the sides of blouse.
1. Fold the material into two folds with the locked part towards left and mark it at a length of 14 inches. On the top, measure 7 ½ from the left towars right and mark it. From thst point draw a line straight below at 7 inches. Now as shown in the image mark the chest from the left towards right at 11 inches. Mark at a point at the right side by measuring the length below from the chest at 4 ½ inches. As shown in the next image measuring from the left towards right, mark at 5 inches on the line of chest. Similarly mark at 6 inches on the point that falls at 4 ½ inches below chest. Mark the pattern for the neck as well. As shown in the second image, give such a sort of a mark. Now draw the pattern as that in the third image. The points marked earlier needs to be followed.
1. Cut as shown
The parts that are to be kept are shown below, while the other are to be discarded.
1. Fold a piece of cloth having a length of 4 ½ inches and breadth of 16 inches in the centre. Keep the closed part on the left. Measure 4 inches at the top from the left towards right and mark it. From this point draw such a pattern towards right that goes down 1 inches below. Cut it along this line. Open the fold and cut in the centre to make two equal parts. Stitch a dart allowance at the centre that begins at 1 ½ inches from below and ends at the top in a slanting manner. As shown in the second image below.
1. After the dart allowance has been done, the piece stitched looks like the one below in the second image. Stitch the rest of the pieces as shown.
For the back part of the blouse, a simple cutting is necessary as we do for a simple
1. Join the shoulder tops of both sides.
1. Now add a piping 1 inches wide and stitch at both the sides at the front where hooks have to be added as shown in the image below. Tuck it in neatly and do a hemming at the front blouse part where hooks have to be stitched while the other part that will remain below needs a fine stitch. Stitch a piping throughout the neck of both front and back parts and also the arm opening and tuck it in neatly. Use can do a fine hemming or a machine stitch.
1. Add dart allowances at the back part of the blouse. Now stitch the sides.
