Quick answer
The easiest way is to attach a safety pin or bodkin to one end of the drawstring and work it through the casing, then secure the ends. This works for most casings, whether in hoodies, pants, or bags.
Why the method matters
Threading a drawstring through a casing can be frustrating if you don't use the right technique. A safety pin or bodkin gives you control and prevents the cord from bunching or twisting inside the casing.
The width of your casing should match the thickness of your drawstring. A 4 mm cord fits neatly into most standard casings, but if your casing is narrower, the cord may drag or get stuck.
Choosing the right drawstring
For most projects, a smooth nylon drawstring slides more easily through a casing than a cotton one. Nylon also resists moisture and wear, making it a good choice for items that get washed often.
Look for a drawstring with finished ends, like plastic tips, so it doesn't fray while you thread it. If your cord has raw ends, seal them with a lighter or a dab of fabric glue before you start.
Step-by-step: How to thread a drawstring
- Prepare the drawstring: If your drawstring doesn't have finished ends, seal them with a lighter or fabric glue to prevent fraying. Attach a safety pin or bodkin securely to one end. Check that the safety pin is smaller than the casing opening; otherwise it will get stuck.
- Insert the drawstring into the casing: Push the safety pin into the casing opening and begin working it through, bunching the fabric along the cord as you go. Use your fingers to guide the pin from the outside. Work slowly and keep the cord straight to avoid twisting inside the casing.
- Pull the drawstring through: Once the pin reaches the other opening, pull it out gently. If there is no second opening, you'll need to create one or use a different method. If the pin gets stuck, pull the fabric back slightly and re-guide the pin rather than forcing it.
- Secure the ends: Remove the safety pin and tie a knot or add a cord lock to the ends. Make sure both ends are even before securing. Test the drawstring by pulling both ends; it should move smoothly without catching.
