Why Traditional Wool Blankets Are Worth Repairing

In a glen cottage, few things work as hard as a good wool blanket. It has likely seen decades of use — draped over a chilly bed in a stone-built farmhouse, folded on a pew at the kirk, or spread on the grass at a summer fete. Traditional blankets woven from Scottish wool are dense, warm, and remarkably forgiving. A small hole or a frayed edge is not the end of a blanket's life; it is simply an invitation to sit down by the fire with a needle and a bit of patience.

Unlike modern synthetic throws, wool can be darned, felted, and gently washed without losing its character. Repairing by hand also keeps the blanket out of landfill and saves you the cost of a replacement. With a few evenings of work, your blanket can pass down another generation.

Gathering Your Darning Kit

You do not need a sewing machine or specialist equipment. A simple kit, kept in a tin or basket, is enough for most repairs. Choose a darning needle with a large eye and a blunt tip so it slips between the wool fibres rather than splitting them.

• Mending wool: Use pure wool yarn in a matching or slightly darker shade. Crewel wool or fine knitting yarn works well, but avoid acrylic, which will not felt into the old fibres.
• A darning mushroom or egg: This holds the fabric taut and lifts the area you are working on. A smooth, rounded stone from the burn will do at a push.
• Sharp scissors: Small embroidery scissors are ideal for trimming loose threads.
• A soft brush: A clothes brush or a clean nailbrush helps lift the nap after washing.
• Wool wash: A pH-neutral liquid detergent made for lanolin-rich fibres, never a biological powder.

Darning Holes and Thin Patches

Start by trimming any ragged edges around the hole, but do not cut into sound fabric. Place the damaged area over your mushroom so the weave is flat and slightly stretched. Thread your needle with a length of wool no longer than your forearm — long strands wear thin and knot.

Work a series of parallel stitches across the hole, running from sound fabric on one side to sound fabric on the other, about 5mm apart. Do not pull tight; the wool should sit like a tiny bridge. Then weave a second set of stitches at right angles, passing over and under the first set. This creates a small woven patch that mimics the blanket's original structure.

For thin, worn patches rather than holes, you can felt a little carded wool over the area. Tease the fibres loose, lay them over the thin spot, and rub gently with a little warm soapy water and your fingertips. The wool will mat together and reinforce the fabric without a visible patch.

Reinforcing Edges and Binding

Blanket edges take the most punishment. A frayed selvedge or a worn binding will unravel further if left alone. Turn the blanket to the wrong side and look at the edge. If the binding is sound but the blanket fabric beneath is thin, stitch a strip of wool binding or a length of wide woollen tape over the edge, catching both layers.

Use a blanket stitch along a raw edge for a neat, traditional finish. Bring the needle up through the fabric about 1cm from the edge, pass the thread behind the needle, and pull snug. Space each stitch evenly. This holds the fibres and looks deliberate rather than mended.

If the blanket has a fringed end, check for loose threads and re-knot any that have come undone, trimming the rest to a tidy length.

Washing and Reviving Wool Gently

Never put a traditional wool blanket in a hot wash or a tumble dryer. Fill a bath or a large tub with lukewarm water — no more than 30°C — and add a capful of wool wash. Submerge the blanket and let it soak for 15 to 20 minutes. Gently squeeze the water through the fibres; do not rub, wring, or twist.

Drain the tub and refill with clean lukewarm water to rinse. Repeat until the water runs clear. To remove excess water, roll the blanket in a clean towel and press down. Lay it flat on a dry towel or a sheet over a clothes horse, reshaping it to its original dimensions. Dry away from direct heat or sunlight, which can yellow the wool.

Storing for Many Seasons Ahead

Once dry, brush the nap gently with a soft brush to lift the fibres. Fold the blanket rather than hanging it, which can distort the weave over time. Store it in a cotton pillowcase or a breathable bag, never in plastic, which traps damp and encourages mildew. Add a few sprigs of dried lavender or a cedar block to deter moths.

Air your blankets on a dry, breezy day once or twice a year. A few hours on a line in the glen will freshen them without any washing at all. Look over the edges and any previous darns, and catch small problems before they grow. With that simple routine, a well-loved blanket will keep you warm for many winters to come.
