A hand-worked buttonhole is a small piece of structural sewing. It must look calm on the cloth, but it also has to withstand the pull of a button passing through it. On linen, where the weave is visible and the fabric can fray readily at a cut edge, preparation matters as much as the stitching itself.
The method below uses a narrow straight opening with a rounded end. It is suitable for a shirt front, cuff, simple dress opening, or other light-to-medium-weight linen garment. Work a trial buttonhole first on a scrap of the same linen, using the same layers of interfacing or facing as the garment.
Materials and preparation
Gather the intended button before you mark anything. The buttonhole must be made for that particular button, not for a stated button diameter alone. A thick shell, wood, fabric-covered, or shanked button needs more room than a flat button of the same width.
You will need:
- Linen garment fabric, prepared with any facing, placket, or lining already assembled
- Matching sewing thread for stabilising stitches
- Buttonhole twist or a firm embroidery thread for the edge stitching
- A hand-sewing needle that passes easily through the layers without making a large hole
- Small, sharp embroidery scissors
- Tailor’s chalk, a removable fabric marker, or a fine pencil suited to fabric
- The button that will be used on the garment
Buttonhole twist is traditionally useful because it is smooth, firm, and slightly rounded. It gives the edge a clear corded line. If using stranded embroidery floss, keep the number of strands consistent throughout. Ordinary sewing thread can work for a very fine buttonhole, but it is less substantial and usually needs more care to avoid a thin, weak edge.
Before beginning, press the garment area flat. Linen responds well to a firm press, and a smooth surface makes accurate marking easier. If the buttonhole lies in a placket, waistband, cuff, or facing, make sure all layers are aligned and securely basted or stitched together before working the opening.

Measure and mark the opening
1. Find the buttonhole length
Lay the button on the linen and measure its widest part. For a flat round button, this is its diameter. Add a small amount for ease so the button can pass through without straining the stitches. The necessary ease depends on the button’s thickness and the density of the fabric; a thicker button needs a little more than a thin one.
Rather than relying only on a measurement, mark a tentative length on a scrap and test it. A buttonhole that is slightly too short is difficult to correct. One that is much too long can gape, especially on a vertical opening.
For a horizontal buttonhole, which is often useful where the garment will be pulled sideways across the body, the rounded end may take some of the strain. Vertical buttonholes are common on a front opening where the pull is largely downward. Follow the garment’s construction and the direction in which the button will be stressed.
2. Mark the position
Mark the centre line of the garment opening first. Then mark the buttonhole line at a right angle to it, or in the direction required by the design. Use a ruler or a folded paper guide to keep several buttonholes level and evenly spaced.
At each end of the marked line, make a tiny cross mark or dot. These are the stopping points for the cut and the stitch line. Keep marks fine. Broad chalk lines can be difficult to remove from pale linen and may encourage imprecise work.
3. Stabilise the area
Linen is prone to shifting and fraying, so a buttonhole should not be cut into a single unsupported layer. A facing, placket, or a small patch of suitable interfacing on the wrong side gives the opening a firmer foundation. The stabilising layer should suit the weight of the linen: too heavy a support can make a graceful garment edge feel stiff, while too little support allows the buttonhole to stretch.
If there is no built-in facing, a small piece of fine linen or lightweight interfacing may be placed behind the intended opening. Secure it neatly before marking and cutting.

4. Sew a small running or backstitched outline
Before cutting, secure the marked opening with a close line of small running stitches or backstitches just outside the future cut edge. This is not always visible in the finished work, but it helps hold the layers together and gives a boundary for the buttonhole stitches.
Place these stitches evenly around the opening, leaving enough room inside them for the cut. Avoid pulling the thread tight enough to pucker the linen.

5. Cut the slit carefully
Fold the fabric very slightly along the marked line and make a small initial snip at the centre. Open the fabric and continue cutting toward each end with sharp scissors. Stop just short of the end marks rather than cutting through them.
A narrow opening is easier to enlarge than a cut that has gone too far. If you are uncertain, cut the slit a little short and test the button only after the edge stitching is partly in place.
For the rounded end, do not cut a large hole. The curved end is formed mainly by the arrangement of the buttonhole stitches. A small, controlled termination to the slit is enough.
6. Begin the buttonhole stitch
Thread the needle with a manageable length of buttonhole twist. A thread that is too long twists, catches on the linen, and loses its smooth finish. Anchor the thread on the wrong side or within the seam allowance where possible.
Bring the needle up at the cut edge. Insert it a short distance away from the edge, then bring the point out through the cut opening. Before pulling the thread fully through, pass the working thread under the needle point. Draw it through so that the little knot, or purl, settles directly on the cut edge.
This is the essential buttonhole stitch. The purl forms a raised protective rim; it should sit along the opening rather than on the garment surface.
Work each stitch in the same direction. Keep the depth of the stitches consistent and place them close enough together that no raw linen edge shows between them. On fine linen, close small stitches generally look better and protect the edge more reliably than broad, sparse ones.
7. Keep the sides even
Stitch along one long side toward the far end. Let the thread lie naturally as you pull each stitch snug. Tight pulling can draw the opening out of shape; loose pulling leaves an untidy edge that catches on the button.
If the linen begins to pucker, pause. Smooth the fabric flat with your fingers, check that the stabilising layer has not shifted, and continue with a slightly gentler tension.
Use the first side as a visual guide for the second. The stitches do not need to be mathematically identical, but their spacing, depth, and angle should appear steady when viewed from a short distance.

8. Shape the rounded end
At the end of the slit, make the stitches slightly closer together and fan them around the curve. The outer edge of each stitch should follow a small semicircle, while the purls remain close to the cut edge.
A rounded end is built gradually. Avoid trying to turn a sharp corner with one or two large stitches. Several small stitches make a smoother curve and distribute strain better.
Continue down the second side, then work the remaining rounded end in the same manner. If the design calls for a bar at one end instead, the end may be reinforced with several straight stitches laid across the opening and covered with close buttonhole stitches. For an ordinary rounded buttonhole on linen, however, matching curved ends are usually the quieter choice.
9. Secure the thread
Finish on the wrong side. Take two or three small securing stitches through the stabilising layer or into the back of the buttonhole stitching, without carrying thread across the open slit. Trim the thread close.
Do not knot on the front of the work. A visible knot interrupts the clean line of the edge and can catch when the button is used.
Test and finish
Press the surrounding linen lightly from the wrong side, using a pressing cloth if the thread has a sheen that might be flattened or marked. Do not press heavily across the buttonhole itself; the raised purls should remain distinct.
Test the opening with the actual button. Push the button through in the direction it will be used. It should pass with a little resistance, then rest securely without distorting the linen. If it is difficult to pass through, carefully remove one or two stitches at the tightest point and trim the cut edge by a very small amount before restitching that area. Make changes slowly.
If the buttonhole gapes, check whether it is too long, insufficiently stabilised, or placed in a direction that receives sideways strain. A badly oversized opening is best addressed by remaking the garment section when practical; trying to close a long buttonhole with extra stitches often leaves a bulky, visible repair.
Mistakes worth avoiding
Cutting before checking the button
A buttonhole cannot be made reliably from appearance alone. Always test the proposed length on a layered scrap, particularly for thick or irregular buttons.
Using a blunt or oversized needle
A blunt needle can snag linen fibres rather than part them cleanly. An oversized needle leaves holes beside the stitches, making the buttonhole edge look rough.
Working without support behind the linen
A single layer of light linen may stretch or fray under use. A facing, placket, or discreet backing layer gives the stitches something stable to hold.
Pulling every stitch as tight as possible
Firm stitching is not the same as tight stitching. The buttonhole should be dense and secure while the surrounding linen remains flat.
Rushing the curved ends
The ends receive repeated strain. Small, close stitches arranged patiently around the curve are more useful than a hurried cluster of large ones.
A well-made hand-worked buttonhole need not be perfectly uniform to be successful. Its value lies in an even protected edge, a shape that suits the button, and a finish that belongs naturally to the linen garment. With a prepared foundation and steady stitch tension, it becomes both a useful fastening and a modest detail worth seeing up close.
