And then you have the difference between Bronze and Silver Twinkles, which is a matter of footwork.
In Bronze Waltz, the leader would go L-Forward, R-Side, L-Close (This may turn a bit to get you into proper alignment of where you want the twinkle to end, if you are going around a corner, probably doesn't need to turn, if you are in the middle of a wall, need to turn it so your promenade is facing at a diagonal, so you continue down line of dance.).... As you lower, you turn into Promenade and the R Leg Extends between partners R-Forward, L-Side (bring partner to face), R-Close.
In Silver Waltz, the difference is on the first 3. L-Forward, R-Side, ***L- Brushes to meet R Foot and then steps out*** (Usually involves more turn then the bronze version, but less than a spin turn.) R- Step through, L-Side (bring partner to face), R-Close.
Hope this helps. (Any corrections, welcome, too.)
