just remeber... dont dry stuff that have just been fiberglassed on cloth hangers... they will get bent and will look like they are drooping... this is my own experience.. i messed up my torso this way... i have to fix the shoulder strap things now my torso looks like a rectangle.
oh.. now on topic.. remember to cut the line NEATLY.. and on the top of the helm, make sure it is all straight or else it will look lopsided...
