Sorry to bother you about this, but I have looked over all of your instructions, and I cannot, for the life of me, figure them out. I think there's too few steps. I'm not one to complain, and I'm not complaining, I'm just saying, I can't quite read it.
The only advice I can give you is: improvise the internal structure. You see how it should look, so place the outer pieces where you want them and create a skeleton that can support.
