1/2 Tag (or "Half Tag", or "Half Tag the Line") starts the same way as a Tag the Line. Each dancer turns 1/4 (90 degrees) toward the center of their line. They all then start to do a Double Pass Thru, but don't go all the way through. Instead, they stop halfway, to end in a box.

Like Tag the Line, 1/2 Tag can be done from any kind of line of four.

Note that the original center from each half of the line walks forward to take hands with the original end from the other half of the line.

Because the dancers are passing right shoulders, the result is always a right-handed box.
