Transform humble fabric squares into brilliant borders
CORNERSTONES
The term ‘cornerstones’ refers to
simple squares of fabric that can be
sewn into each corner of a quilt border.
They’re ideal for introducing an accent
colour or pretty print to a quilt and are
just right for jazzing up plain borders! In
the six steps below, we show you the
simple way to add cornerstones to a quilt,
sewing them to the border strips before
attaching to opposite sides. As always,
remember to include seam allowances
when you cut your fabric.
Once you’ve tried this method, you
can get creative with the design of
cornerstones. Not only could you use
difference fabrics, but the squares
themselves can be patchwork. Why not
incorporate Half-square Triangles?
STEP ONE
Cut four border strips to fit
each of the four sides. They
should all be the same width,
including seam allowance.
STEP four
Pin one of these border units
to the side of the quilt,
aligning the cornerstone
seams carefully.
STEP two
Pin and sew two of the strips
to opposite sides of the quilt.
STEP five
Sew the unit in place and
press. Add the other border
strip to the other side of the
quilt in the same way.
STEP three
Cut four squares the same
height as the strips. Sew
a square to each end of the
remaining two border strips.
STEP six
Check the finished quilt top
is regular and right-angled.
Press the seams outwards,
towards the edge of the quilt.
