Not waving,but drowning...sometimes

The BBC Poetry Season starts soon

I hope to write one a day. If you write poetry how do you go about it?
Do you think of a subject or,like me,does it start with a few words that you like
I liked "half-discovered wings"
So this....

She flew
On half-discovered wings
Budding not blossoming
Cobwebs in her cauldron
Potions of yesteryear
Opaqued by dust
The crystal ball's clarity
Eluded her
Fanciful claims
