LENGTH OF STRIP-WINGS 131 



shank still left exposed, and wind in tight and 

 even coils in the reverse way back until the 

 roots of the hackle are reached. These coils 

 of silk form what is known as the " bed " or 

 foundation for the wings, which it is necessary 

 to form for every kind of wing. 



Now take two strips, exactly matching, and 

 carefully placed one on top of the other, and

measure the required length, as shown in 

 Fig. 49. (In strip-wings generally the wings 

 should not project much beyond the hook 

 i.e., beyond a line drawn at right angles to the 

 shank, and just touching the bend, like the 

 tangent of a circle. In Spey flies there should 

 be no part of the wing to the left of or posterior 

 to this line.)
