A cut wool blanket edge does not always need a complicated binding. The best finish is usually the one that keeps the cloth flexible, contains loose fibres, and suits the way the blanket will be handled.
For most fulled wool, three hand-finished edges are useful: a visible blanket stitch, a closely worked overcast edge, or a narrow turned hem. Blanket stitch is the most decorative and helps hold a plainly cut edge. Overcasting is lighter and less conspicuous. A turned hem gives the firmest appearance, but it adds a little bulk and is best where the cloth is not too thick.
Before sewing, test the wool and the thread on a scrap. Wool can change in size or thickness with washing, steam, or damp handling, and a thread that seems suitable in the hand may pull sharply against the cloth.
Choose the finish
| Finish | Best suited to | Character | Main caution |
|---|---|---|---|
| Blanket stitch | A visible, sturdy edge on a cut blanket | Clear and traditional | Uneven tension can draw the edge inward |
| Overcast edging | A soft, simple finish with little added bulk | Quiet and flexible | It may not contain a very loose edge on its own |
| Narrow turned hem | A firm, tidy edge on lighter or moderately thick wool | Smooth and restrained | Thick fulled wool can become stiff at the fold |
A blanket stitch is the most forgiving choice when the edge is freshly cut and likely to be handled. Choose overcasting when the wool is already quite stable and you want the stitching to recede. Use a turned hem when the edge needs a clean line, such as on a small throw or a blanket made from relatively thin cloth.

Materials and preparation
Gather the blanket, a scrap of the same wool if possible, fabric scissors, a measuring tape, and a needle suited to the thread. A blunt tapestry needle works well with wool yarn and reduces the chance of splitting the fibres. A sharp sewing needle is more useful for ordinary cotton or linen thread and for making a turned hem.
For thread, match the weight to the cloth. Wool yarn gives a soft, integrated appearance and is suitable for blanket stitch or overcasting. Strong cotton thread can be used when a finer, less prominent line is wanted. Avoid a thread so fine that it cuts into the edge, or so heavy that the stitches stand stiffly above the blanket.
Trim only the loose, uneven fibres. Do not cut deeply into sound cloth merely to make the edge perfectly straight. If the blanket is badly irregular, mark a restrained line with chalk or a removable fabric marker, using the existing weave or edge as a guide.
Test for shrinkage and tension
Cut a small piece from a similar offcut, or use a hidden portion of comparable wool. Finish one side with a few inches of the intended stitch. If the blanket will be washed, test the sample in the same general way, following the care method you expect to use. Let it dry fully before judging the result.
Look for three things: whether the wool changes size, whether the stitched edge puckers, and whether the thread becomes slack or cuts into the cloth. If the sample draws up, use longer stitches, a lighter thread, or a looser hand. The finished edge should lie flat without being pulled tight.
How to sew a blanket stitch
Blanket stitch forms a line of separate loops along the edge. It is particularly suitable for a cut wool blanket because each stitch crosses the raw edge and helps keep loose fibres from spreading.
-
Mark the spacing. Begin with stitches about 6 to 10 mm apart, adjusting to the thickness of the wool. Heavier cloth can take wider stitches; a fine blanket usually looks better with closer ones. Mark only a short section at first so you can judge the scale.
-
Anchor the thread. Bring the needle from the back near the edge, leaving a short tail to secure later. If using wool yarn, do not make a bulky knot. A few small securing stitches within the edge are often less noticeable.
-
Make the first loop. Take the needle from back to front at the next marked point, keeping the working thread beneath the needle point. Draw the thread through the loop so that the horizontal part of the stitch rests along the edge.
-
Continue evenly. Work along the edge with the needle entering at a similar distance from the cut edge each time. Keep the loops upright and gently snug, but do not tighten them until the wool gathers.
-
Secure the end. At the last stitch, take one small stitch in place or pass the needle beneath the base of the final loop. Fasten on the wrong side, then bury the thread tail between the wool fibres or under nearby stitches.
The distance from the edge matters as much as the distance between stitches. If the needle enters too far in, the stitch may leave a fringe of loose wool outside it. If it is too close, the thread can slip out of the edge. On a thick blanket, let the needle travel through the body of the cloth rather than catching only the surface fibres.
Turning a blanket-stitch corner
At an outside corner, work the final stitch on one side, then place two or three stitches into the same corner area before turning along the next edge. This fills the point without forcing one stitch to cover too much distance.
At an inside corner or a small notch, shorten the spacing and take a small supporting stitch if needed. Corners should not be pulled sharply. It is better for the corner to have a little extra thread than for the surrounding wool to pucker.

How to work an overcast edge
Overcasting is a simple stitch that passes diagonally over the cut edge. It is useful when you want the wool to remain soft and the finish to be less prominent than blanket stitch.
Start by anchoring the thread just inside the edge. Bring the needle up on the back, pass it over the raw edge, and insert it again from front to back a short distance along. Repeat the diagonal movement, keeping the stitches close enough to catch the loose fibres but not so close that they form a hard cord.
For a stable, closely fulled wool, stitches about 5 to 8 mm apart may be sufficient. A looser or more open edge needs closer work. Judge by the cloth rather than by a fixed measurement: the edge should remain contained when lightly brushed or handled.
Overcasting can be worked with wool yarn in a matching shade, or with strong cotton thread for a finer line. If the thread is visible, a closely related colour usually looks calmer than a stark contrast. If the edge is vulnerable, the thread can be placed slightly farther into the cloth on the second pass, but avoid making a second rigid row unless the blanket truly needs reinforcement.
At a corner, make one stitch immediately before the turn and one immediately after it. If the corner is bulky, take a small diagonal stitch across the point rather than wrapping the thread repeatedly around the same fibres.
How to sew a narrow turned hem
A turned hem is neat, but it is not suitable for every wool blanket. Very thick fulled cloth may resist a narrow fold and become noticeably stiff. Test the fold before committing to the whole edge.
- Mark a turning line on the wrong side, usually no wider than the cloth can fold without strain. A narrow hem is easier to keep flat than a broad one.
- Fold the edge to the wrong side and finger-press it. If the wool will not hold the fold, use a few temporary tacking stitches rather than pressing aggressively with heat.
- Thread a sharp needle with strong, fine thread. Make small slip stitches or catch stitches, taking only a little of the blanket’s surface on each pass so the stitches do not show prominently on the right side.
- Work a short section, then check that the hem is not drawing the edge inward. Remove and redo any area that feels tight before continuing.
- Secure the thread inside the fold and trim the edge only after the hem is stable.
A turned hem is most successful on lighter wool or on an edge that has already been cut cleanly. For a thick winter blanket, blanket stitch often gives better movement and avoids a hard ridge.

Keeping the edge even
Let the blanket rest on a table or other broad surface while you sew. Supporting only the section in your hands can stretch the edge and make the spacing appear correct until the cloth is laid flat again.
Use short lengths of thread. Long thread tends to twist, abrade, and tighten unevenly as it passes through wool. If the thread begins to kink, let the needle hang and unwind before continuing.
Check the reverse side from time to time. Large carried threads, knots, or tight loops can catch during use. A good finish is secure on both sides, though it need not be perfectly identical.
Common mistakes to avoid
- Pulling every stitch tight. Wool needs room to move. Snug the thread only until it rests against the edge.
- Using a fine thread on a thick edge. It may cut into the fibres or disappear while leaving the edge unsupported.
- Making the stitches too far apart. Loose spacing can leave sections of a cut edge uncontained.
- Forcing a turned hem on heavy cloth. If the fold feels springy or bulky in the sample, choose overcasting or blanket stitch instead.
- Ignoring the corners. A straight run may look sound, but corners need closer spacing and a little extra support.
- Washing before the edge is secure. Finish the whole perimeter and inspect the stitching before laundering the blanket.
A practical recommendation
For most cut wool blankets, begin with a blanket stitch in matching wool yarn. It is clear enough to inspect, adaptable around corners, and capable of holding a slightly unsettled edge without adding a separate binding. Choose overcasting when softness and discretion matter most. Choose a narrow turned hem only after a sample shows that the cloth can fold without stiffness or puckering.
The finished line should feel like part of the blanket rather than a tight cord laid on top of it. Even spacing, moderate tension, and a careful test piece will do more for durability than elaborate stitching.
