Finally I've got it sorted!!! There are three versions to this pattern as you've probably realised!!!
There's the simple one with just double picots, another with a simple long beaded picot and the third has two long beaded picots which interlink. There's a page here which will explain this better if you get stuck!!!
Now there is something interesting about this little motif which I'm quite pleased with.
I've used two beads in each one placing them 'back to back'. These sequins have two holes in them (which you'll need for the pattern) BUT if you've only got one hole at the edge it's really easy to 'poke' another hole opposite with a pin or needle!! I've tried it!!!
