Two years ago I did a short class at a local craft show that was teaching Viking Weave (or knit). The class taught how the viking weave could be made by working around a mandrel. After the chain is complete it is then drawn down through a draw plate using ever smaller holes to give you the completed chain.
One of the beauties of this weave is that it is so forgiving - drawing the chain down can potentially hide a multitude of errors - other than drawing it down too soon thus leaving you with a chain thats too short! At a pinch even that can be corrected but you wouldn't want to have to do that too often - the time I did it I ended up with massive blisters - not fun!
Viking Weave can be done in either single weave, to give you a lacy look, or double weave for a firmer more solid look - this tends to be the weave that I do. You can leave the chain as is, its actually a lovely chain in its own right, or you can add embellishments to it, for example sewing small beads into it. Either way - you can end up with some lovely looking pieces.
