1-2 2s step up;
9-40 All three couples are moving continuously in these sash pin reels, never stopping. As an aide-mémoire, each corner reaches and passes through his/her original corner position at the end of each 8-bar phrase, stopping only at the end of bar 40.
9-16 The sash pin reel with first corners is an 8-bar combination of a half reel of 4 on the first corners' diagonal with a chase clockwise halfway around the corners' square; 1s are followed by partner's first corner, 2 bars behind; second corners dance in to the centre to meet and turn so that 1s and first corners can chase through second corners' positions, unimpeded. Timing is of the essence: 2 bars for each quarter of the diagonal reel of 4 and for each side of the corners' square in the chase; second corners have a quite sedate movement and so must be particularly careful not to get ahead of the music. The chase should follow the rectilinear shape of the corners' square, with a sharp change of direction at the halfway corner, rather than a sloppy oval; this helps with timing as well being more satisfying to the dancers and any spectator.
17-24 The sash pin reel with second corners is an 8-bar combination of a half reel of 4 on the second corners' diagonal with a chase clockwise halfway around the corners' square; first corners dance in to the centre to meet and turn so that 1s and second corners can chase through first corners' positions, unimpeded.
25-32 This sash pin reel is exactly as in bars 9-16 but starting with 1s facing partner's first corners.
33-40 This sash pin reel is as in bars 17-24 but starting with 1s facing partner's second corners. Corners finish facing in, 1s cross by the right to finish in 2nd place on own sides, facing out (except on the final repeat when they pull right shoulders back to face in).
-40 On the 1st, 3rd, 5th and 7th repeats, 1s finish in 2nd place, facing out, ready to dance as 1st couple again.
On the 2nd, 4th and 6th repeats, 1s also finish in 2nd place, facing out, ready to cast to 4th place of the full set in bars 1-2 of the next repeat WHILE the new 3s step up.
On the last repeat, 1s finish in 2nd place of the active set (3rd place of the full set), facing in.

This dance, Mary MacNiven's Sash Pin, is so-named because it is a derivative of James B. Cosh's dance, Mairi's Wedding, on the fairly safe assumption that Mary would have worn a sash at her eventual wedding to John Campbell.
