Tartan Hose look pretty much like Argyle hose.  The ones I make have 3 diamonds around the cuff at the top, but can have 2 or 4.  The Main color diamonds alternate down the center front of the legs.  Main color diamond can be split into 4 quadrants and different solid colors can make up the big diamond.  Off to the side are diamonds of mixed colors, which are called Marled diamonds. Stripes cross the diamonds to mimic the stripes in the kilt tartan.
