Hybridizing hibiscus

[Aliamyz]

Hi guys & girls,
Besides a nepenthes enthuasist, i am also a collecter of hibiscus plants.
I have some beautiful blooming plants which i've tried pollinating them before but failed many times.
You guys with any success would like to help me?
I've learn that seed grown plants from the parent pod may differ from the blooming style, leaf structure and may end up with eye-catching flowers.

This website shows how to pollinate hibiscus but i've failed.
Any help will be apprecited!
