Rucksack/backpack Repair: Replacing a Strap Adjuster

When I was getting off a Eurostar in Brussels this summer on Scout camp, a strap on my heavy rucksack caught on something, and the strap adjuster snapped. Thinking only of the train leaving for Rotterdam quarter of an hour later on the other side of the station, I put the adjuster in my pocket and forgot about it until I had come back home and seen replacement adjusters in John Lewis.

So, in this instructable I'll show you how to fix on one of these replacement strap adjusters. You can buy other replacement plastic parts as well, so you may be able to replace other parts with this technique.

Step 1 Tools and Materials

Tools
- Scissors
- Needle

Materials
- Strap adjuster. I found mine in John Lewis' Haberdashery section. Measure the width of the strap before you buy.
- Strong thread. I used button thread for this.
- Normal thread. This is just for the stitching that prevents fraying, so it should be thinner.
