When I started tying one of my first molds was a mold with a collar. At that time most of what you could get was collared. Then I found Do-It molds and they had collarless. So I learned to tie with both. Today I tie 98% of my jigs on no collar blanks.Shoemoo's tutorials will help you just be careful and watch your proportion. Jig Tiers are Artist and so it is really up to you to to do what YOU want to have them come out looking like. I don't care what mine look like a lot of time What I care more about is will they catch fish. If they look great and catch fish it is a added bonus. Remember for most of us this is a Hobby and is for having fun.
