my first bow style that i really wanted to learn & started was the twisted boutique... Didn't happen overnight. Practice, practice, practice... Mastered.
I could never master pinwheel... Definitely not my bow-BFF that's for sure and I stayed away from this style.
I agree with ellisandbrileesmom.
Start whichever bow you feel like mastering and the site she mentioned is a good start. Michelle's free instructions will be a good start too.
The EASIEST is the bow-tie style... JMHO tho. How To Make Bow-Tie Hairbow/Hair Bow Clips--1--Ribbon Bows : Hip Girl Boutique - , Ribbons, Hair Bows, Hair Clips, Hairbow Hardware, Free Hairbow Instructions
