This pattern is easy and fast.. But there is a trick: don't use soft textile thread, take softlex-like base instead. And I use fishing line for that chain. Work fine!
Tripple chain might confuse you a little. But don't worry!
It's better to try it on beads with large halls or even pony beads.
Notice that you have to string 3 beads to begin. Than you'll add 2 beads at each step.
