Once Removed calls from columns and lines are very similar to each other in that they are both done from 2x4 matrices and many of the same calls work virtually the same within each type of formation.
These calls include but are not limited to
| Couple Up | Counter Rotate | Mini Chase | Wheel the Ocean/Sea | |
| Walk and Dodge | Square Thru | Star Thru | Slide Thru |
Many calls done in the basic 2x4 formations are not taken out - they are danced within each box.
The red dancers work in the same group as the blue dancers and the green dancers work with the yellow dancers.
Simple calls like Square Thru are done in each Once Removed box with no interaction between boxes except for the obvious passing required.
Calls from facing line formations like, for example, Once Removed Star Thru or Once Removed Slide Thru, change the formation from a line formation to a column formation. A Once Removed Partner Trade retains the line orientation.
There are box of four calls that can not be done from the Once Removed boxes, like Square Chain Thru. These calls require a take out. These calls may be done differently from Columns and Lines/Waves depending on some of the parameters of the call. For example, Once Removed Catch 2 dances differently from Once Removed Catch 3. The Catch 2 from Columns ends in lines and the Catch 3 from columns ends in columns.
This take out can be easily done by having the lead center step aside, away from the formation, step backward and step back into the column while the trailing center moves into the vacated spot. The put back at the end of these calls, when there is one and the final formation is a column, is to do the same movements. This call is called Substitute. It was removed from all lists in 1984 but is particularly relevant in this situation.
Substitute looks like this:
Sometimes calls that start in columns end in lines or waves, sometimes in tidal formations and sometimes back in columns.
Let's look at four examples:
Once Removed Catch 2 from Columns
Once Removed Catch 2 from Lines
Calls from columns, lines and waves sometimes end up in a tidal formation. These calls are not Once Removed when the call is over. The Once Removedness of the original formation must be restored. If the call was not taken out at the beginning of the call, the Once Removedness is restored using the DROP method. If the call was taken out at the beginning of the call then the Once Removedness of the original formation must be restored using the DRAG and DROP method. See the section - Calls that End in a Tidal Formation - for additional discussion.
This is a typical example.
Once Removed Beau Hop
This call uses the DROP method to restore the Once Removedness of the formation.
