How to make a draught excluder: a simple DIY with what you have

A step-by-step way to make your own fabric draught excluder, plus when it is easier to buy one.

Making a draught excluder is a classic afternoon project, and it is a good way to use up leftover fabric. Here is a simple way to do it.

What you need

  • A strip of fabric about 100cm long and 25cm wide (more or less depending on your door).
  • Thread and a needle, or a sewing machine.
  • Filling: polyester stuffing, dry rice, dry lentils or fabric scraps.
  • A funnel or a rolled-up piece of paper for filling.
  • Scissors, pins and a tape measure.

Step by step

  1. Measure the door. Measure the width of the bottom edge, and add 2cm. That is the length you want.
  2. Cut the fabric. Cut a rectangle the length you measured by about 24cm wide. A thicker fabric such as cotton drill or corduroy holds up better than thin cotton.
  3. Fold and pin. Fold the fabric in half lengthways with the right sides together, and pin along the long edge.
  4. Sew. Sew along the long edge and across one short end, with a seam allowance of about 1cm.
  5. Turn it out. Turn the tube the right way round and push the seam out neatly.
  6. Fill it. Use the funnel to fill the tube. A mix of stuffing at the ends and rice in the middle gives weight without lumps.
  7. Close the end. Fold the raw edge in and sew it closed with small stitches.

Making it work better

  • Weight matters. A light excluder slides away. Use rice or lentils for a heavier excluder, or add a layer of bean bag pellets inside a second inner tube.
  • Keep it dry. Natural fillings can go mouldy if damp, so use polyester stuffing for a damp hallway.
  • Make it washable. Use a zip or make the cover removable with a separate inner tube.

When to buy instead

A homemade excluder is lovely, but it is still a loose tube. If the door is used constantly, or the gap is large, a fixed seal is more reliable. Compare ready-made excluders with fixed door seals before you start sewing.

Ideas for a child-friendly version

A sausage dog or a snake with felt eyes is a popular project, and a good one to make with children. Use safe, non-toxic materials and keep small parts such as buttons off the finished item.

Quick answers

What can I fill a homemade draught excluder with?

Dry rice, lentils, fabric scraps, polyester stuffing or old tights all work. Heavier fillings such as rice stay put better but can attract pests if they get damp, so keep them dry.

How long should a homemade draught excluder be?

About the width of the door, or a few centimetres longer. Measure the bottom edge of the door before you cut your fabric.

Is it cheaper to make one?

If you already have fabric and filling, yes. If you need to buy materials, a ready-made one can cost about the same.
