I have a question for you veteran foam/cardboard builders. Ive been building paper pep for a little over a year and I love that every piece connects to another piece BUT I hate having to deal with all the tiny details during glassing and filling. HOW do you know what pieces go where when you do foam/ cardboard? I mean I know some pieces go ON TOP of others while some join at the same faces they would in paper pep... I REALLY wanna try foam/cardboard for the speed factor, but its looking a bit intimidating to me at the moment. ANY help would be REALLY appreciated.... Thanks.
