Why Linen, and Which Weight to Choose

Linen is one of the few textiles you can trace from field to furnishing without a single synthetic input. Flax grown in Northern Europe needs little beyond rainfall, the whole plant is used, and the fibre that comes out of it is stronger than cotton, quick-drying and naturally resistant to dust mites. Better still, it softens with every wash, so a hand-sewn linen cushion becomes more inviting the longer it lives on your sofa.

For a cushion cover, choose a medium-weight, pre-washed linen of around 190–260 gsm. Anything lighter will let the shape of the pad show through; anything heavier is a wrestling match when you turn the corners. If you are buying fresh cloth, wash and tumble-dry the length once before cutting. Linen shrinks most in its first wash, and you would rather that happened now than after you have stitched a 45cm square by hand. Worn sheeting, faded tablecloths and dressmaking remnants are all fair game.

What You Need Before You Cut

• Fabric: 1.1m of 150cm-wide washed linen for one 45cm cover, plus a little extra for bias strips
• Piping: 5mm cotton cord and enough bias binding to run a little over 1.8m
• Thread: 100% cotton or linen thread, matching or a shade darker than the cloth
• Needles: sharps or betweens, size 7 to 9, and a thimble that actually fits
• Notions: fine silk pins, tailors' chalk, small sharp shears, a 45cm cushion pad

Measuring and Cutting the Panels

A cover should finish 1–2cm smaller than its pad, so that the pad fills it plumply rather than sagging. For a 45cm pad, cut one front panel 45cm square and two back panels 45cm by 30cm. From the leftovers, cut 4cm-wide bias strips and join them with narrow diagonal seams until you have a continuous length of about 1.9m.

Mark with chalk and cut along the grain of the weave rather than the edge of the table. Pull a single thread from the fabric and use the line it leaves as your guide — linen has a lively mind of its own once it is off-grain. Press every panel flat before you go any further.

Making and Attaching the Piping

Fold the bias strip in half lengthways, wrong sides together, and press. Lay the cord into the crease and tack it with small running stitches worked close to the cord but never through it. Then pin the piping to the right side of the front panel, raw edges level, so the cord sits exactly on the 1.5cm seamline.

At each corner, snip the piping seam allowance almost to the cord — four or five little cuts — so it turns a crisp right angle instead of a puckered curve. Tack the whole length by hand. This step feels slow, but it is the reason a hand-stitched cushion looks tailored rather than homemade.

A Concealed Opening at the Back

The two back panels overlap to form a deep envelope, which hides the opening completely in the middle of the reverse. Hem the inner long edge of each panel with a double turn of 1cm, pressing as you go, then slip-stitch the hem invisibly with tiny stitches that pick up only a thread or two of the cloth.

Overlap the panels by 15cm and check the finished width against your front panel. If you would like extra reassurance, work two buttonholes by hand into the overlap and sew on matching buttons — but on a cushion this size the overlap alone holds perfectly well, and the pad keeps everything in place.

Stitching the Seams by Hand

Lay the front panel right side up, then place the two back panels right side down on top of it, overlapping in the middle and aligning all four raw edges. Pin every 4cm, keeping the pins perpendicular to the seam so the fabric cannot shift.

Work a row of backstitch all the way round, using 2–3mm stitches and a 1.5cm seam allowance. Backstitch is slow but it is genuinely strong: each stitch doubles back on the last, giving a seam that will not gape when the cushion is stuffed. Use your thimble on the push, and keep the tension even — linen shows every tight stitch.

At each corner, stop with the needle down, pivot, and carry on. Trim the seam allowances to 1cm, snip the corners diagonally about 3mm from the stitching, and overcast the raw edges together with a whip stitch so the inside is as tidy as the outside. Turn the cover through the envelope opening and poke the corners out gently with a blunt pencil.

Pressing, Stuffing and Aftercare

Press the cover from the wrong side over a damp cloth, coaxing the piping flat and rolling the seams between your fingers as you go. Steam is linen's best friend; a hot iron straight onto the cloth is not. Insert the pad, easing it into the corners rather than forcing it, and give the cushion a firm pat into shape.

To care for it, wash by hand or on a cool 30°C cycle with a gentle detergent, dry flat or on the line away from harsh sun, and press while slightly damp. Avoid tumble drying once the cover is made. Treated kindly, a hand-sewn linen cushion will outlast three machine-made ones — and look far better doing it.
