My dad taught me how to make bracelets out of knotted colourful thread (or yarn) when I was younger. We stuck to the simple “diagonal stripes” design, but upon researching links for this post, I’ve discovered that the patterns you can do are almost endless, achieved by changing up the types of knot you tie at each stage. Friendship-bracelets.net has a lot of information on this.
Think of it like knitting. A knitting pattern will tell you which type of stich to do and how many; similarly, the instructions will tell you what strand order to start with and which knots to tie in what order.
The great thing about these bracelets is that you can make them with whatever colours you can get, and you can change it up to get whatever you like. On top of that, it makes a soft, light, low maintenance piece of casual “jewellery”. The finished product will slowly fade and stretch out, and any time it gets wet it’s a little annoying, but it’s something that can make any outfit look more fun, summery and “boho”, and if you’re willing to put in the time and effort, you can make something (for a friend or for yourself) that’s 100% unique and personalised, for a very low cost.
