I’ve never been able to switch from z to s twist. The video really helped me see how it works. What would happen if you didn’t switch the tama before changing from one twist to the other? I make a lot of necklaces with a focal bead in the front center and switching will make mirrored patterns. Would you start the necklace in z and do the second half in s or does it really make a difference? Thanks so much for your guidance.
