The title gives you an order with a deadline, sow these seeds in August. The thumbnail repeats the order in big letters and points at a tiny seed between two fingers, but never says what it is. August only comes once a year, so you need to know which seeds before the window closes.
How the packaging works
Title
The title gives the order and the deadline but never names the seeds.
Thumbnail
The thumbnail shows a seed too tiny to identify, held between two fingers.
Remix this
If your advice only works at one time of year, put the deadline up front and show what you mean without naming it. It's fine to repeat the deadline on the thumbnail, as GrowVeg does, so nobody misses it.
The transferable lesson
When timing matters, lead with the deadline and show the seeds without naming them.
