It's really fast and easy, it took me about 10minutes to make even with the beads refusing to be threaded on, so I hope you have a go :)
Step 1: What You Need
•alphabet beads. I got a packet for £1 from a craft shop so I don't think they're hard to find.
•jewellery endings. Not sure what they're called but those little metal things with a hook on the end. Also clasps and chain.
