From lines of four, waves or two faced lines: Face Down the Line and then perform a Tag the Line movement as directed by a Dixie Chain procedure--i.e., leaders step up and join right hands (1/4). Leaders pull by with a right and join lefts in parallel waves (Dixie Half Tag). Leaders pull by with a right, then a left and the trailers join right hands in the center wave (Dixie Tag Three Quarters). Those trailers pull by with a right and all end in completed double pass thru formation on a regular Dixie Tag.
