Finally, after more than one month, I managed to scrape out a peaceful afternoon (not without my son's help) and make a second Twinnlino pendant the colours of which I liked even more than those I had chosen for the first. But alas, after sorting out the beads I realised that one rondelle was missing: there were 7 of them instead of 8. What could I do?
Since I'm not new to 7-pointed stars, I decided to try all the same and make adaptations while working, if needed. In fact, only one adaptation was necessary, that is, to add one 15° seed bead at both sides of each 4mm Swarovski in order to compensate for the wider angles between the points (see photo 2).
