Mystery Knit Along - Clue 3

Clue 3 was released without any errors and I used the time on my flight to Chicago to knit.  I was able to finish between the waiting for the flight and the actual flight.  I was lucky to get a window seat where the middle seat was blocked and I had someone with super long legs sit on the aisle seat.  Pretty comfortable until we landed in Chicago where it was a "balmy" 12 degrees.

I like the pattern as it looks like scales.
