One of our students asked about using the newly launched rondelles with the Russian Spiral technique. Yes, it can be done. Here is a small section, stitched with the 6 x 4mm rondelles with 3mm Swarovski crsytal pearls. For 1.5" section, I used 33 rondelles and 66 pearls/beads. Thus, for 17" length (it will shrink to 16" due to the bulkiness of the cord), you will need about 380 rondelles and 750 units of pearls/beads.
From my experience, Size 8/0 seed beads (which is almost equivalent to 3mm beads) are not suitable when working with rondelles. This is because the rondelles are wide and flat, so you need the round beads to fill in the gaps nicely. You do not have to use crystal pearls, any round beads are fine.
For light coloured beads, you may like to use the crystal white Fireline or Nymo thread as bits of threads can be seen.
