Material need for Canadian smocking depends upon the flowing things
1. Size of the finished material we need.
2. Design we select.
3. Size of the square in the graph we use for smocking.
For each design I have arrived at a general formula using mathematics .By just substituting the numbers in the formula we can find out the width of the material by calculating how many squares we need in a row. We can calculate the length of the material needed by calculating how many squares we need in a column.
Diagonal of the square plays a great role in this. I will give you approximate values diagonals of the squares we normally use.
Diagonal of a square of 2 cm =2 .8 cm
Diagonal will be for square of 2 .5 cm = 3.5 cm
Diagonal will be for square of 3 cm = 4.2 cm
Diagonal will be for square of 4 cm= 5.7 cm
Method of calculating material need for a cushion of "Arrow head design"
Cushion size 40 cm X 40 cm
Arrow head design
Size of the square used in the graph= 3 cm
General formula to calculate width of the material
No of squares needed in row = (width of the finished smocked material needed x 4) ÷ diagonal of the square
General formula to calculate length of the material
No of squares in a column = (length of the finished smocked material needed X 2) ÷ Diagonal of the square
Method of calculating the width of the material
No of squares needed in a row = (40 cm X 4) ÷ 4.2 = 38 squares
Material needed for 38 squares =38 X 3 cm = 114 cm
Width of the material needed =114 cm + 2 cm for seams =116 cm
Method of calculating the length of the material
No of squares in a column = (length of the finished smocked material needed X 2) ÷ Diagonal of the square
No of squares in a column = (40 cm X 2) ÷ 4.2 = 19 squares
Material needed for 19 squares =19 X 3 cm =57 cm + 2 cm for seams =59 cms.
Please note that the number of squares in a row should be of even number.
First row and last row are smocked by joining 2 points
The remaining rows are smocked in pairs by the method of joining 3 points.
In the same manner we can calculate the material needed for different sizes of cushions done with different sizes of squares.
