The Shrunken Wool Rescue: A Pattern-Free Lined Hat for Beccles Mornings

Some of the best sewing material in Beccles is hiding on the charity-shop rail in plain sight: a wool jumper that has been washed too hot, worn too often, or simply forgotten. It has gone dense and slightly matted. The sleeves may be a bit short. It is, in other words, ready to become a hat.

Felted wool is forgiving. It does not fray like a woven cotton, it holds a shape, and it keeps the wind out on the walk home from town. This project turns one shrunken jumper into a lined, bobble-topped winter hat without a paper pattern. You will cut two rectangles, sew two tubes, and anchor a pompom with a button. If you can sew a straight line and thread a needle, you can do this.

First, find a jumper that has already done its shrinking

Charity shops around Beccles are ideal hunting grounds. The rails along Blyburgate and Smallgate often have a few men's XL jumpers that yield enough fabric for a hat and a pair of mittens besides. Look for 100% wool or a wool-rich blend that already feels dense and slightly stiff. Hold it up to the light: if the knit looks tight and matted rather than open and drapey, it will work beautifully.

Check the underarms, seams and cuffs for holes. A jumper with a stain on the front can still make a hat from the back. Avoid anything that still feels soft and loose — you want the fibre to have already tightened. If you find a lovely wool jumper that has not felted, you can shrink it at home with a hot wash, but that is a separate experiment. For this hat, start with the already-shrunken ones. They are usually cheaper, and they already have the texture you want.

What you need

• One felted wool jumper
• About half a metre of lining fabric: cotton jersey, an old t-shirt, or lightweight fleece
• Matching all-purpose thread
• A ballpoint or stretch needle for the lining, and a universal needle for the felted wool
• Clips or pins
• Tape measure, scissors, tailor's chalk
• A small button
• Yarn or a faux-fur pompom for the bobble

The pattern-free measurements

Measure around the head just above the ears. For an adult hat, a rectangle about 56–60cm wide and 30–33cm tall works well. The width is the head circumference plus 2cm for seam allowance. The height is the distance from brow to crown, plus about 10cm for the turn-up and seams. Cut one outer rectangle from the felted jumper and one lining rectangle the same size. The lining can be 1cm shorter so it does not peep below the brim.

Use the body panels of the jumper rather than the sleeves, unless you are happy piecing. Cut slowly and keep the grain straight. Felted wool does not shift much, which makes this a kind cut for a beginner.

Sew the outer and lining tubes

Fold the outer rectangle in half with right sides together, matching the short edges. Sew a 1cm seam to make a tube. Repeat with the lining. Press the seams open with a cloth and a moderate iron.

Now close one end of each tube to make the crown. Run a strong gathering stitch around one opening of the outer tube, about 1cm from the raw edge. Pull it tight and secure the thread. Repeat for the lining. This gives a soft, slightly slouchy top — exactly right for a bobble hat.

Turn the outer tube right side out. Leave the lining inside out. Slip the lining inside the outer so the raw bottom edges line up. Sew around the bottom edge, leaving an 8cm gap for turning. Turn the whole hat right side out through the gap, then slip stitch the gap closed.

Sewing knits without drama

Felted wool is stable, so a normal straight stitch usually works. The lining may stretch, though, so use a ballpoint needle and a narrow zigzag or stretch stitch. Do not pull the fabric as you sew. Clips are kinder than pins on thick wool, and they hold the layers without leaving holes.

If your machine complains about the knit, sew the lining by hand with a small backstitch. Press seams with a cloth and moderate heat; wool can scorch if you are impatient with the iron.

The bobble and the button anchor

Make a pompom from yarn using two cardboard rings, or use a faux-fur pompom from a craft shop. Attach it at the crown. To stop it wobbling, sew a small button inside the crown and stitch through the hat and the button several times. This spreads the strain and keeps the bobble sitting proud.

If you want a detachable bobble, use a press stud or a large snap, but a fixed one is more secure for windy mornings by the Waveney.

Fit, finish and care

Try the hat on before you slip stitch the turning gap. It should sit just over the ears without pressing. If it is too loose, take in the side seam. If it is too tight, reduce the seam allowance. Hand wash cool, reshape and dry flat. Brush the wool gently to bring up the texture.

A small note on sourcing

Beccles charity shops, car boot sales and jumble sales are all fair game. Look at the label, check the seams, and do not overlook the men's rail. One jumper can become a hat, a pair of mittens and a few patches. That is slow sewing in the best sense: one garment rescued, one warm head, one less thing in the bin.
