This necklace was one of the first. I made it by incorporating large beads with ribbon and some elasticated see-trough string.
The other necklace I made after seeing this on Pinterest.
And this is how...
1st row is quite straight forward. Start with the large knot (double, triple if you need to) and then tread trough 8 longish beads.
2nd row is most difficult one as it's not established and you constantly need to keep it tight while working with it. So, start with looping over 1st row three beads back.
3rd row is quite simple: tread one bead then loop trough the 2nd row then repeat the same until the middle of the row.
