The following are examples of Figures where Diagonal covering may need care.
Diagonal covering in Scottish Country Dancing is particularly difficult. Although, as in Mirror covering, the dancers can see each other reasonably well, their relative Positions are not intuitive and are difficult to maintain. The line joining the Covering dancers' Positions must always pass through the Centre of the Active set and the dancers must be equidistant from the Centre; although this is a fixed Position, there is no marker for it and so the dancers can only guess. This rule applies to the Corners as well as the Dancing couple; the Corners should not attempt to Cover as though these were Mirror reels.
