After a long, long layoff I've only recently returned to fly tying (and fly fishing) in the last 18 months.
I know the basic tying techniques (in fact I've tied respectable fully dressed salmon flies in the past

) but at the moment I'm being defeated by beads. I just can't get them on the hook as they don't seem to want to go round the bend without me bending the hook!

I'm using Kamasan B175's (14's and 12's) and Veniards 3.8mm beads.
Hopefully this is a real numpty question and someone can provide a answer that has me thinking 'well slap my vitals, why didn't I think of that!' Is there a secret technique? I won't tell anyone else. Honest!
