Method of calculating the fabric needed for smocking done by joining two points-
Measurement of the cushion= 40 cm x 40 cm.
Size of the squares on which
smocking is done= 2.5 cm x 2.5 cm
Design= " Leaf design".
Two columns of squares marked with
diagonals are worked together while smocking.
These form one column of smocked design.
These columns are separated by columns
of gaps on which smocking is not done.
Two columns of diagonals are separated
by one column of gap. These are
repeated to get the measurement we need.
Last two columns should be
of columns with diagonals.
So there will be even numbers of smocked
columns and gaps will one less.
In the above design square which are
marked green are the squares on
which smocking is done.
Draw a square of side 2.5 cm and measure
its diagonal. If we are accurate
it will be 3.535. Let us take 3.5 cm.
After smocking 4 squares of the
first column (filled with red stripes) the
width will be half of the diagonal that is 1.75 cm.
The length will be equal to the
diagonal of the square that is 3.5 cm.
There will be no change in the
measurement of gaps
Keeping this calculation as basis
we have to find out the number of
squares we have to mark in each row
and how many rows we need to
get the size of cushion we need.
Width of 2 smocked squares + 1 gap
= 1.75 cm + 2.5 cm =4.25 cm .By dividing
the width of the cushion by 4.25.
40/4.25 = 9.41
We have to repeat the design
9 times 4.25 x 9= 38.25
Last column of smocked squares =1.75 cm
So we need 10 pairs of columns marked
with diagonals separated by 9 columns of gaps.
We have to mark 29 squares in each row
Width of these squares after smocking will be
1.75 cm x 10 no’s =17.5 cm
Width of 9 gaps =2.5 cm x 9 =22.5 cm
2.5 cm border added on each side for
seams and for wastage while stitching.
2.5 c m x 2 no’s =5 cm
Total =17.50 cm +22.50 cm + 5 c m= 45 cm.
After smocking 2 rows will be equal to
the diagonal of the square we are working on.
Length of 2 rows after smocking =3.5 cm
Divide length of the cushion 40 cm by 3.5 cm
40/3.5 cm= 11. We have to repeat
these two rows 11 times.
We have to mark 22 rows.
2.5 cm border is added on each side
for seams and for wastage while smocking.
Width= (2.5 cm x 29) + 5 cm =77.5 cm
Length= (2.5 cm x 22 rows) + 5 cm = 60 cm
In the same way you can calculate the
material needed for cushions of different
sizes and of different designs .If you
change the measurement of the square
of the graph calculate the diagonal
accordingly and proceed.
following the above graph
Canadian smocking by joining 2 points Shell design
In shell pattern two dots are connected with
pulled stitches which are knotted and
separated by a slack knotted stitch.
Mark squares of 2 .5 cm x 2.5 cm on the
wrong side of the fabric. Mark the red
diagonal lines that represents pulled
stitch. Mark the numbers 1,2,3,4,....while learning,
as it will be easier to follow the diagram.
.Stitch with 3 strands of Anchor thread of
the colour that matches the fabric. Folds look
good if satin material is used.Follow the steps
and stitch all the rows.2 rows of the squares
are used at a time. I have explained them
with images. please see below.
