What are you using as a bobbin?

AWG21 is easy to work with, not so insanely fine that it breaks easily, 
not so big as to be too stiff to work with.


How much voltage are you planning to have across these inductors?  There 
are different winding patterns, some of which have better HV performance 
than others.

For instance winding a "bottom layer" going one direction and a top 
layer going the other direction puts high voltage between adjacent windings.

while doing a (harder to do, but works better) alternate keeps the 
voltage stress lower:
