Row 3: To start a hole, treat the warp as two separate sections of basic sprang, ending one section before starting the next. (To start with more than one hole, add (2F/2B) for as many holes as you want.)
Row 5: To add a hole directly to the right of an existing hole, and in the row below, continue normally until there are 5 threads (including top and bottom) left before the hole. Then sprang 2F/B to end the section and add a new hole.
To close a single hole temporarily (while keeping its column), close the hole with 2F/2B.To add a new hole to the left of an existing hole, after closing the hole, begin the next section of basic sprang with F/2B.
Row 7: Add a new hole to the right, temporarily close the previous holes, add a new hole to the left.
Row 9: Close the rightmost column of holes permanently by continuing the basic sprang until only one thread remains before the hole, then close the hole with 2F/B. Keep the central two holes by closing them with 2F/2B.
Close the left hole with a F/2B to remove the column permanently.
Row 11: Close the right and left columns of holes, keeping the middle one.
Row 13: Return to basic sprang, closing the last hole.
A wide variety of diagonal patterns can be made, as in this detail from a sprang baldric:
