Fishin Bill,
you'll see by JC's post above he doesn't consider it a sheet bend and indeed it is different but similar...well he's gone so he'll probably let that go.....
And since he is gone I'll tell you what bit of heresy I did a day or two ago....I think anglerdave is correct.... you have to eyeball a little tag....well it seems to me that projects even just a little and must make the tag subject to clipping on the guides or picking up debris....both of which I hate....

so I left the tag even longer and folded it back parrallel along the fly line and superglued the tag to the fly line....very smooth transition...no increase in diameter [even less].

Certainly not something you'd do out fishing.....
