Those really do look quite nice! I'm not sure if they are made with varigated yarn or separate skeins of plain colors. The colors are much nicer than what I have to work with. Here are some examples of the type of yarn, if you could just imagine the colors in "prison uniform" orange (or maybe it's "traffic barrel" orange), "dark brown suit", and well, cream is cream.
I just don't know if it's worth doing all the work of the pattern stitches if the color is so crazy mixed up that maybe no one will notice. I might keep it under wraps, beneath a bedspread.
