A skein of yarn is easier to use once it has become a loose, orderly ball. A wooden yarn swift provides the gentle turning surface that makes this possible, holding the skein open while the yarn is wound by hand or fed to a separate ball winder.
The design below is a small umbrella-style swift. Its four arms fold inward around a central post, while a sliding collar and wooden links open them to different sizes. It does not need elaborate joinery. Straight-grained wood, careful drilling, and smooth edges matter more than ornament.
The measurements are a starting point rather than a fixed pattern. A swift with arms about 450 mm long will suit many ordinary skeins, while longer arms will accommodate larger hanks but make the tool more cumbersome.
Materials and tools
Choose a light but durable hardwood with clear, straight grain. Maple, beech, ash, birch, and similar woods are suitable. Avoid pieces with knots near the arm ends or short grain across narrow sections.
You will need:
- Four straight hardwood arms, each about 450 mm long, 20–25 mm wide, and 10–12 mm thick
- A hardwood dowel for the central post, about 20–25 mm in diameter
- A small hardwood block for the upper hub
- A sliding wooden collar that fits over the central post
- Four narrow wooden links for the opening mechanism
- Small bolts, washers, and nuts for the arm and link pivots
- Wooden pegs for holding the skein
- Wood glue
- Sandpaper from coarse to fine grades
- Shellac or hardwax finish
- A wooden base board, clamp, or other steady support for the finished swift
A handsaw, drill, bits matching the bolts and dowel, rasp, square, pencil, and small clamps are sufficient. A block plane is useful for reducing the arms evenly, but it is not essential.

Prepare the arms
-
Mark four matching arms. Cut the pieces to equal length and mark the centreline on each one. Consistent arms help the swift turn without a pronounced wobble.
-
Round the outer corners. Ease the corners and ends with a rasp or sandpaper. The yarn should encounter no sharp edge as it passes around the swift. Round the lower edges as well, especially near the pegs.
-
Mark the pivot holes. At the inner end of each arm, mark a hole about 20–25 mm from the end. Keep every hole at exactly the same distance from the end and centred across the width.
-
Mark the peg positions. A useful arrangement is one fixed peg near the outer end and two or three additional peg holes spaced along the arm. The pegs should stand upright and be snug enough not to fall out, while still allowing the swift to be adjusted.
Drill the peg holes before final sanding. A hole that is slightly shallow can be deepened; a hole drilled too loosely is harder to correct. Test each wooden peg as you work and label the matching peg and arm if their fits differ.
Do not make the arms unnecessarily thin. They must remain stiff when a skein is pulled gently around them, but their edges should be comfortable to touch. A modest bevel along both long edges will prevent fibres from catching.
Make the hub and central post
The upper hub holds the four arm pivots. It can be made from a hardwood block roughly 60 mm square and 25–30 mm thick. Mark the centre of the block, then mark four pivot positions around it at equal intervals. The holes should be arranged like the points of a compass, with enough space between them for the arm ends to move without rubbing.
Drill a vertical hole through the centre of the hub for the central post. The post should pass through smoothly but without excessive side play. If the post is too loose, the swift will rock; if it is too tight, the folding action will become stiff.
The post may be about 300–400 mm long, depending on how the swift will be supported. If it will sit in a base, leave enough length below the hub for the base and above it for the sliding collar. A simple base can be a thick wooden board with a carefully fitted hole. The board should be broad enough that the swift does not tip as the skein turns.
Round and sand the post thoroughly. The sliding collar must travel along it without catching on raised grain or a sharp corner.
Add the folding mechanism
The umbrella action comes from four links running from the arms to a sliding collar below the hub. When the collar moves upward, the links push the arms outward. When it moves downward, the arms fold toward the post.
Make each link from a narrow strip of hardwood about 180–220 mm long. Round both ends. Drill a pivot hole at each end, keeping the holes aligned and equal on all four links.
Attach one end of each link to the underside or lower outer edge of an arm, roughly halfway between the arm pivot and the first peg. Use a small bolt and washer rather than glue. The link must move freely, and the washer should keep its edge from rubbing directly against the wood.
Attach the other ends to the sliding collar. The collar can be a short hardwood cylinder or a square block drilled through to fit over the central post. If using a square block, soften its corners so yarn and hands cannot catch on them. Drill four evenly spaced holes around the collar for the link pivots.
The collar should slide with light hand pressure. If it binds, do not force it; check that the post is straight, the collar hole is square to its faces, and the four links are the same length. A little extra clearance is preferable to a mechanism that locks when the wood changes with humidity.
Fit the arms to the hub with bolts and washers. Tighten the nuts until the arms have no troublesome side-to-side movement, then loosen them slightly if the arms do not swing freely. If the bolts turn while you tighten the nuts, hold the head carefully with a spanner or choose bolts with a square shoulder suited to the hole.

Fit the pegs and establish the size
The yarn rests against the pegs rather than directly on the arm tips. Use smooth wooden pegs with rounded tops. They may be turned, carved, or made from short lengths of dowel with their ends carefully rounded.
Place one peg near the end of each arm. Additional peg holes closer to the hub allow the swift to hold smaller skeins. Keep the arrangement identical on all four arms so the skein remains balanced. The pegs do not need to be tall; 35–50 mm above the arm is generally enough to keep a loose hank in place.
If a peg hole is too tight, enlarge it gradually with a drill or round file. If it is too loose, the peg may wobble under tension. A small shoulder at the base of each peg can help it seat consistently, but avoid a shape that creates a ledge for yarn to catch upon.
Open the arms evenly and measure the distance from one peg to the opposite peg. This is the approximate diameter of the skein the swift can hold. It is better to leave a little room than to stretch the yarn tightly across the pegs.
Smooth and finish the wood
Take time over every surface that may touch yarn. Sand the arm edges, peg tops, bolt areas, hub, collar, and central post until they are clean and smooth. Run a scrap of fine cotton cloth over the parts; if it snags, keep sanding.
Do not leave loose dust in the peg holes or around the pivots. A soft brush or cloth will remove most of it. Avoid heavy, glossy finishes that create a thick surface around moving parts. Two or three thin coats of shellac, lightly rubbed between coats, will seal the wood. A hardwax finish is another suitable choice. Keep finish away from the pivot threads and allow it to cure fully before bringing yarn near the swift.
The contact surfaces of the collar and post may be left lightly waxed rather than heavily coated. The goal is a smooth, dry-running movement, not a slippery tool that is difficult to control.
Mount and test the swift
Set the central post into a stable wooden base or secure it to a firm work surface. The support must not rock. A swift that shifts under tension will make the yarn tighten and slacken unevenly.
Open the arms with no yarn fitted. Turn each arm through its full movement and watch the hub from above. The tips should describe a reasonably even circle. A small difference is tolerable, but a large wobble usually points to unequal arm lengths, an off-centre pivot, or a link mounted at a different position.
Place a skein over the pegs and lower the collar until the arms hold it gently. The yarn should stay in place without being stretched taut. Turn the swift slowly by hand, using a little tension on the yarn as it leaves the skein. Listen for scraping and watch for snagging.

Useful mistakes to avoid
- Over-tightening the pivots: The arms need controlled movement. Tight bolts can make the swift jerk or refuse to open.
- Using short-grained wood: A peg hole or pivot near a weak grain line can split when the mechanism is adjusted.
- Leaving square edges: Even a small sharp corner can catch fine wool, silk, or loosely spun yarn.
- Making the peg holes inconsistent: Different positions on the four arms make the skein sit crooked.
- Skipping the balance check: Test the empty swift before adding yarn. Problems are easier to correct at this stage.
- Applying finish before fitting: Finish can reduce hole sizes and make a previously smooth joint bind.
- Pulling hard while winding: A swift is meant to support the skein, not stretch it. Use only enough tension to guide the yarn into a ball.
A wooden swift rewards patient fitting. Once the arms open evenly, the pegs hold without catching, and the hub turns quietly, it becomes a modest but useful companion to ordinary winding work. Folded closed, it takes little room; opened beside a chair or workbench, it lets a skein unwind in an orderly circle without plastic parts or unnecessary complication.
