Grading contd.....

There are certain factors that you must take into consideration when grading.

(The following information is for size range 8 -16.)

1. Design proportion

2. Design Detail

3. Fabric

4. Trimmings

5. Size range

6. Machinist cost

7. Graders cost

8. Fabric marker

9. Nil grade areas

Nil Grade Areas

1. Any small pieces for example; tabs, yokes facing widths, cuffs, collar width, pleat width, frills, waistband width

2. Tucks and darts

3. Back shoulder dart, waist dart, elbow dart, back and front skirt darts, nil grade in length.

4. Frills and flounces, nil grade in width only - but length must be graded in proportion to the garment.

Some would same that button spacing is a nil grade and as you grade up you gain extra length and to add an extra button. I don't agree with this I always grade my button spacing accordingly for every size to keep them in proportion. You are not always able to add another button it depends on how much length grade you add. So I always calculate and maintain the correct proportion for the buttons.

Button size always remains the same size throughout. Lace, braid and applique are a set size.

When you consider fabric take into account factors such as repeat patterns, stripes, checks, floral, border prints, one way prints, etc.

Pattern notches should always remain in the same position and try to use the least amount of notches as it is easier to work with.

Please note that insleeve length, skirt length and inleg to ground length can vary from manufacturer to manufacturer as some of them grade the lengths of skirts, pants and sleeves and their grading rules may also vary from the grading rules that I have mentioned above. However in menswear and childrenswear these lengths will definitely grade. You would subtract or add these measurments between sizes 8 to 16 depending on what size you use to start your grade.

I will be posting some lessons shortly on how to grade using the measurments above on various designs, so please stay tuned.
