baseball caps

I've seen a handful of makers use these instead of balaclavas for bases and it's a method I'm considering as an alternative for a balaclava. I like the results of balaclava base heads, but sometimes they drive me crazy --mainly my hair...no matter what I do it always goes crazy underneath. I'm thinking it'd be more helpful as far as getting airflow as well which would be nice.

My question is -- does anyone have progress pics of this? I'm trying to envision how one would go about foaming on top of a cap and I'm a little lost. I'm sure everyone has their own method, but any advice on this technique would be great. I'm going to attempt building a very short muzzled critter so I'm not sure if that will make this method more or less effective. I'd like to start with the muzzle if I can kind of to keep things centered, so I was thinking of using a wire down the middle and maybe mounting my muzzle on that and kind of build from there? Any tips would be great!

Also, I'm considering using plastic comes over buckram to achieve a certain effect, but I've heard they can fog up pretty badly (and I already wear glasses so fogging up is a big no no for me) and just wondering if a head has good ventilation is fogging up of these domes a problem?
