Duh! I see what I was doing incorrectly. I formed and tied the loop to the lead hook and then tried to push the doubled end through the hook eye after the popper was tied. Putting the ends through first would be easier no doubt. Replacing the hook, though, will take some doing.
Now I'm regretting leaving for a trade show in the morning. I could be fishing instead... I wonder if my boss would mind me not showing up... thank heavens the show is shorter this year, and I return Friday afternoon.
Surging bow wakes are cool, but I really like having a pod of three or four fish competing for my fly or in this case, popper. That can be a real double-shot espresso experience.
Now if I can stay focused and get my work done in advance, I can have September off. Guess I better get back at it.
