Well, looks good for your first try. Armor is not too different from spaceships, really. Only more mud.
Oh and btw. I heard many people fake the cloth on those boxed with paper tissues. They sometimes only have reliefes on the outer edges. Usually they are free of them. Many use white glue and water on them.
Lookin good Scott. Your on the right track. If i do a tarp i use patterened tissue. once its wet and hit with glue the pattern tends to come out of the tissue. Your aves worked just as well though. If you have any other questions PM ME!
