White Ranger Helmet: Part 4

I added a second layer of paper mache.  One thing I have run into is material warping.  It may be that I'm using too much of the glue mixture, but I'm sure that if I had some sort of way to keep the inside braced (a mannequin head with my dimensions for instance) I could avoid this issue.  For now, I'm just keeping an eye on the helmet as it's drying and occasionally putting some pressure with my hands on the parts that need to keep their shape.  What is giving me the most trouble with movement is the line where the visor hole meets the mouthpiece hole.  

I figured that some of the warping was being caused by gravity.  I have the helmet standing on its own (no stand, mannequin, etc.) so the weight of the helmet is likely causing the material to bend while it is drying.  Since I don't have a mannequin head or anything else for now, I just propped it up on a can of lysol spray (the tallest can I had) to prevent any pressure points for the next layers.  When you are working on yours, keep warping in mind and try to have something in place to keep it from doing so.
