The drawstring has disappeared into the waistband channel

Short answer: Attach a safety pin or a drinking straw to the end of the cord and feed it through the channel. Then sew a couple of stitches at each end, so it does not happen again.

Why it happens

The cord is only held in place by friction against the inside of the channel. Once the fabric has been washed a few times and the channel turns smooth, the cord slips in easily with one hard tug. It happens most often in night pants and joggers, where the cord gets pulled daily.

Getting it back out

Attach a large safety pin to the end of the cord, feed the pin into the hole, and push it forward through the channel while gathering the fabric ahead of it with your other hand. If you have nothing to attach, tie a thin thread to the end and pull it through instead.

When both ends are gone

Never cut into the channel to search for the cord. Instead find the seam at the side of the waistband, carefully pick open a couple of stitches with a seam ripper, and pull the cord out there. Sew the seam neatly back together afterwards, so the waistband keeps its original shape.

How to prevent it

Sew a single stitch through the cord and channel at the centre back, so the cord cannot travel around the waist. Also tie a small, firm knot at each end of the cord that cannot pass through the hole, no matter how hard the pants get pulled during use.

Choosing the right replacement cord

If the original cord is gone, choose one of the same width and material, ideally flat rather than round, since flat cord slides less and sits better in the channel. A cord that is too thin travels more easily, while one that is too thick can be hard to pull all the way through.

Making the waistband last longer

Avoid yanking hard on the cord when tying a bow, and loosen the knot fully before washing, so the channel does not take unnecessary strain. Wash the pants inside out, and use a gentle cycle if the fabric is thin, so friction against the channel builds up more slowly over time.

Joggers and night pants with a wide waistband

A wide elastic waistband with a cord combines the best of both solutions, but the cord has a longer path through the channel there and can be harder to pull back out. Use a long, stiff safety pin or a knitting needle as a tool if the short version is not enough.

When the cord is too short to tie

If the cord has been pulled in and stretched several times, it can end up too short for a proper bow. Consider replacing it entirely rather than lengthening it, since a joined cord tends to snag inside the channel at the next wash. See bamboo night pants for women.

The whole problem is easier to prevent than to fix, so check the knots now and then, especially on clothes worn almost daily. See bamboo jogging suit for men and night pants for men for waistbands that are easy to keep track of.

Frequently asked questions

Can a worn cord be replaced

Yes. Tie the new cord to the end of the old one and pull the old one out, and the new cord follows automatically through the whole channel without any trouble.

Why does it happen more often after many washes

Because the fabric grows softer and the channel smoother over time, so the friction that originally held the cord in place gradually disappears through repeated washing.

Is elastic better than a cord

For nightwear, elastic is often more convenient day to day, but a cord allows a more precise waist adjustment and adapts better to changing sizes over time.
