Easiest fly in the world. Way back around year 2000 I fished something very similar for SMB in the Boundary Waters. Worked well.  Perusing this article brought me back to that pattern. Burning a bit over that concept and the known response that carp offer to SJW and similar patterns...   I dusted off the "yarn worm," restyled a bit and turned out a dozen or so...   the result being my contribution to the most dominant carp swap out there, at Fly Carpin.  In the context of the participants there, I would be a lowly dog.  Lowest, saddest dog.  Depressed, never happy, always-worrying mutt fly tier and aggravated fisherman.  So thanks McTage for the invite.

FYI stands for Yarn Invasion, with a prefixed modifier of your choice. It is thus conducive to loud and confirming exclamations at the point of carp taking this fly.  You can chose to use the abbreviation: FYI you sow biatch!  Or you can spell it all out clearly as line peels off your reel: ****** Yarn Invasion you ****** ****** sow piggy *****!
