Now the top edge is trimmed with a
strip of bias binding. Before I knew
this stuff existed I used webbing brought
from the chandlers. You can use it but it is
stiff to fold and sew. Cotton bias binding
about 1in (25mm) wide is much easier.
Just fold it over the edge and pin it.

Now fold the top edge with the
binding so that it lines up with the
lower chalk line made earlier. You can pin
it in place but double-sided sticky sewing
tape makes it easier. Sew the lower hem
in position.

When you have worked out the
radius I then add about 1in (25mm)
all round for the hem when cutting out the
circle. This extra material makes it easier
to sew and you can put a double seam
into the base to make a really strong bag.
(^17)
Pin the base to the sides and then
tack it in position by hand. I find it
makes this bit easier if you pack out the
tube of material with a pillow or cushions
so it gives you a more rigid column to
work with.
(^18)
With the bag still inside-out sew in
the base. Work slowly and take care
to keep the edge directly under the
needle flat at all times – otherwise it can
pucker and you’ll end up sewing in
unintentional pleats.

Next tack the binding in place by
hand and remove the pins. If you’re
an experienced sewer you probably can
skip this stage but if you’re learning how
to sew like I am this holds things in place
ready for a sewing machine.
(^14)
Fold the material inside out and sew
the outside edges together. At the
beginning and end of a seam it is good
practice to back sew it. This means you
go over it twice for ½in (12mm) or so to
reinforce the stitching and prevent the
end threads coming undone.
(^12)
You can now sew the binding in
place with the machine if you are
using one. With the pins removed it
makes it much easier to follow the curve
without the stitch slipping.
(^15)
Now lay the sewn sides flat and
measure between the seams.
Double this measurement and you will
have the circumference of the circle of
material required for the base. I don’t
know how professionals do it but I use
the back-to-school formula of Pi (/) to
find the radius of the base (see opposite).
