A short-cut method for tie-dying that I use is to put part of the skein into the dyepot and let the other part hang over the edge of the pot (have it supported in some way so the heat or fire does no damage). After that is dyed, turn the skein around so that a new section hangs in the dye liquor. Actually, some of these yarns, when woven or knitted, are quite hideous, unless a deliberate design is planned, so I would experiment in a small way, if I were you.
