For an evocative statement, choose black socks with silver-beaded spider body and silvery moonlit spider web.  If you prefer not to work in black, how about one of the lighter colors with golden sunlit dew drops?  How about a blue and red Spiderman version?  Or choose whatever colors you fancy spiders and their webs to be.  Spider and Web motifs are charted so that you can easily incorporate these designs into other articles.
