The approach
Start with the right question.
Start with a prototype and define what success would look like in water.
In practice
Make it useful on the water.
Test durability and performance; a good-looking lure is not evidence of a good catch rate.
Keep learning
Connect the dots.
Use this guide as a starting point, then compare it with the water you're fishing, the tackle you're using, and your own observations. Good fishing knowledge grows through real practice.
