This is a long skull cap that fully covers the ears.  It's made from Corriedale and Suffolk wool with blue accent stripes in silk and mohair.  Some of the wool is variegated - light/dark with various shades of rose pink.  This is a result of a high content of lanolin in the wool, which causes the dye to react in unexpected ways and adds some extra interest to the design.  The colors are actually deeper than they look in these photos  (at least on my computer).
