My uncle loves fixing bikes. He gave my a whole box of old bike tubes to play around with. This is one of the things I came up with after seeing different versions of belts online.
Btw. you can find some amazing belt buckles around Instuctables, e.g. "Custom Belt Buckles", "Bioshock Belt Buckle in Bronze" or "I Heart Bacon Buckle".
Step 1: What you need
- old bike tube (one with a 4 cm width works best)
- sewing machine
- thick yarn (I used the type you use for leather)
- belt buckle
- Press fasteners
- super glue
- hole punch
Step 2: Sewing
Sewing a bike tube is surprisingly simple. If your machine is having problems, simply add a small layer of oil on top of the tube. I used a straight stitch and after I was all the way around tried it strength. I noticed that the stitch was to weak and I was able to tear it apart.So I added an other stitch next to it, as shown in the pictures. I used super glue to prevent the stitches from opening.
Step 3: Secure the belt
I used Prym "Sport Mini" press fasteners, which turned out to work really well and I had no problem attaching them to the rubber. In order to give them some extra strength I used two, but one should be enough. The fifth picture shows how I marked the spot where the fastener on the other side has to go. Just press the other one down, it will leave small dent.
Step 5: Bonus: USB Bracelet
Put the flash drive between the stitches and cut a slot, through one of the layers (as shown in the third picture). All that is left to do is to add an press fastener and you are good to go.
