As promised, here's a tutorial on how I made my Judal wig! After learning more about spray/expanding foam, I decided to give it a shot since it would be cost efficient and less messy than shaving down normal Styrofoam balls. This youtube video by Mogrymillian is a great intro to using spray/expanding foam! [link]
The awesome part was that it wasn't too heavy! It stayed on my head even before I added wig clips, though I did add some anyway in both the front and back just in case. It only started to feel heavy after I had been wearing it for a few hours.
I'll also go ahead and post photos from using insulation foam and upholstery foam, though I feel the expanding foam is my favorite so far.
