Materials:
- Cushion pads (mine are 40cm x 40cm or 16 inch square);
- Fabric of your choice:
- Make sure you know the size of the cushion pads when you buy the material - calculate how many squares the same size as your cushion could be cut from 1 metre of fabric. From there work out how many metres you need in total;
- Do not buy a really thin fabric because it will need replacing quickly.
- Zips (mine are 12 inches long):
- The length of zip should be less than the length of the cushion pad but not too small that the opening it would give would not be large enough to fit the cushion into.
- Matching thread;
- Scissors;
- Ruler;
- Dressmakers chalk;
- Sewing machine and zipper foot.
Method:
Step 1: Fold the fabric in half (right sides facing
inwards) so that the selvages line up (the frayed edge on the right hand side of the fabric pictured below).
Step 2: Measure your cushion pad. Mine is 40cm x 40cm or 16inch square.
Step 3: Subtract 5cm or 2 inches from the size of
your cushion pad. In my case this gives
a measurement of 35cm x 35cm or 14 inch square.
You want to make the cushion cover as if it were for this reduced size
of cushion pad. This will ensure that
the cushion remains extra plump in its cover.
Step 4: Now that we have the size of the cushion pad
we need to add on the seam allowances. Seam
allowances should be 1.5cm. So you want
to draw onto the fabric a square which is 38cm x 38cm. Measure the shape from the selvage and the
edge of the cut side of the fabric. Cut out
from both layers to give you 2 matching squares.
Step 5: The zip will be inserted into the two edges where the selvage is. Calculate the length of the fabric minus the length of the zip (36.5 - 30.5 = 6cm). This means that when the zip is centred along the length of the cover, there will be 3cm of material left at each end. So we need to keep the squares right sides together and sew through both layers a 3cm seam from the top of the pieces and a 3cm seam from the bottom of the pieces (in the direction of the centre of the fabric). Remember that you need to start sewing these 3cm seams from a 1.5cm distance from the selvage of the pieces.
Step 6: Iron a 1.5cm seam onto the wrong side of the
fabric along both selvage edges.
Step 7: Place both pieces together, selvages at the
top, right sides facing. Pin together
with 3 - 4 pins. Now open the zip and pin
it into place along the selvages. You
want to line up the teeth of the zip with each ironed edge and make sure the
zipper is facing inwards towards the right sides of the fabric. Tack into place.
Step 8: Using your machines zipper foot, sew the zip
into place. Remove tackings.
Step 9: With the zip open and right sides facing, pin
the 3 sides of the square pieces together.
Sew each edge at 1.5cm.
Step 10: Iron the seams open flat. Turn cushion covers the right way out and
insert cushion pad. Plump up and you’re
done!
