Trout dry flies don't float well

[NatalieWTruby]

My trout dry flies don't float well after I've used them for about a half hour even if I keep applying silicone cream, dry fly floatant or sprays. What's wrong?

Time to change to a new, dry, fly?

That's why fishing vests and fly fishing hats have a "drying patch" on them.

depends on the pattern and materials they are made of. Half an hour is awhile. I'd just tie on anpther for same pattern
