white fur, cheap airbrush cons, patterning heads?

hi there! I'm jackal and I've been lurking for awhile and ive trying to gather as much information as I can for a project I wanted to try, my khajiit character from skyrim!! so I guess I'll be asking a lot of questions on really nooby stuff all the time lmao.

soo, the first questions I can think of at the moment are probably pretty simple to answer, although a search through the memories didn't help much ;-;

1. how should I pattern a cat head if its going to be completely white? I've seen that most people cut their duct tape around colors on their heads - but what would be the most simple & easy way to go about this for someone who has no experience?

2. is it really worth the low price to buy a very cheap airbrushing kit? I found one online that's normally $20 and is on sale, but I don't know if getting something extremely cheap will negatively affect the quality of the airbrushing on the head.

3. does anyone have suggestions for white fur that's relatively easy to airbrush and work with for a complete beginner? I'm shooting for a realistic look, but I guess that wouldn't matter..

thank you so much!! sorry for the poor grammar also, I'm on mobile.
