Cheers for the input. I figured it out. Simple really. I moved it forward about a quarter/half inch
Thanks Hersute. I think that's what you were getting at.
Keeping the front lace ultra clean is obviously very important. Can't say enough about paying attention to clean up. I've discovered that tape as far forward as possible is best. Glue really only needs to be literally for the edge.
Vapon notape gets a bit dirty after a day or two. Ultrahold gets a bit rancid, but after my last application (sparingly) it's looking good.

My order of ghostbond just arrived, so I'm looking forward to using that.

In regard to reaction. All have been great. I've now had two people 'have a quiet word' as they are 'fighting the same battle'. That's more of a compliment I think.

I've determined that the color and everything works brilliantly in daylight, normal light etc, but under white light e.g no window bathrooms, it seems to look darker. That might be density. It might be that I haven't colored my natural hair, which has a few greys. Still studying that one.

Really happy. Moving it forward a bit solved the 'off'. Could probably go forward a little more. Will see when cutting down my next.

Loving life. Reborn.
I'm reminded of Paul Newman's last shot in the Color of Money... "I'm Back!"
