Picture below shows a Clyde Style fly of mine that gives one an idea of proportion.
Tied on a med wire size 16 this was conceived by me for Springtime fishing when I needed to get down a wee bitty quicker. Heavier dressed than summer flies but shows the style well never the less.
Tight Lines
PS: There are some examples on Han's site if one has a few minutes spare.
