Borrowing is a means of performing a 3 Couple repeat in 4 couple set dance when only seven Scottish Country Dance Couples are available rather than eight from which two Sets could be made; the name arises because the Top three Couples borrow the Standing Couple from the Bottom part of The set so that they have enough Couples to perform each evenly numbered Repeat.
Unlike the normal form without Borrowing, the dance does not Finish with the Couples back where they started and, except for the Original 2nd Couple, the dancers stand for only one Repeat instead of the usual two.
The sequence is best indicated by the Starting Places for each Repeat with the 1st Couple of the Active sets shown in bold face, the Supporting couples (2nd and 3rd Couples of the Active sets) in roman face and the Standing Couple in italic:
1s2s3s 4s5s6s 7s
2s 1s3s5s 4s6s7s
2s3s1s 5s6s7s 4s
3s 2s1s6s 5s7s4s

1s 3s2s7s 6s4s5s
1s2s3s 7s4s5s 6s
2s 1s3s4s 7s5s6s
Note that it is only in the Bottom part of The set that the Dancing couple Drop one Place after their second Repeat. On completing their second Repeat as the Dancing couple in the Top part of The set (which leaves them in 3rd place of the Full set), they must be prepared to perform as 3rd couple in the new Active set in the Top part of The set.
Equally counter-intuitively, each Couple performing in the Bottom part of The set and arriving at the 4th place of the Full set would expect to be Standing for one Repeat; instead, they must be prepared to perform as 3rd couple in the new Active set in the Top part of The set and, immediately after that, to perform as the Dancing couple in the Bottom part of The set.
This format is not suitable for the Beginner who is likely to have problem enough with the complication of the standard 3 Couple repeat in 4 couple set format.
