In 17-32, the corners traditionally set one bar to the person you just passed, then one bar to the next person to pass. In a variant for [19-24] 1c turns BH in PdB.
Note: The dry white sands on the north-west side of the Isle of Eigg are said to produce a musical sound when walked upon.
Unofficial: On 2nd turn, 4c has an easier start if 1c+3c+4c dance a 3c Poussette
Note: Cosh explicitly tells 1c to pass Lsh in [9-24]; however the Rsh pass is quite common, and nicknamed »Mairi's Divorce«.
