I'm just having another try at asking whether anyone has experience of working with corrugated card and would like to contribute their knowledge to an article for others.

Hi Dave.  I have used corrugated cardboard for several items, but am not sure in what way you are looking for how someone uses cardboard in their PM's.  I use cardboard as my armatures, is that what you mean?

I'm not an artist and I have not been doing this long.  So forgive me if my response is not what you are looking for. 

Beep! Beep! is one of them (My gallery is Vicki Pringle).  I find it so easy to work with.  The entire armature is cardboard - the sides were corrugated and the tops and back is cardboard from the back of a 3 ring binder (because it is easier to bend). 

Omar the Roaring Lion has some corrugated cardboard as well - his face and mane.  His body is a paper canister (an old formula can that the hospital gave me).

So I don't sound like a complete idiot and go into detail on using corrugated cardboard for my armatures, is this what you want information on?

Dopapier, I sent a fairly lengthy email to the address requested on the subject of card for papiermache, I have to assume you did not get it?
