I'm building my very first model so forgive these simplistic questions. I'm building a tank. There are a few sheets of very thin paper (like normal writing paper thickness), which i gather are patterns for pieces i should build out of cardboard and put together, in essensce building an armature for the tank model which i then basically 'skin' with the coloured pieces that are on card stock. Is that right? Also, there is a lot of scoring and folding to be done. How do i know where to score? If i score on the colour side i will marr the surface and if i turn the piece over to score the back of it the lines are hidden so i don't know where to score. There must be a simple solution? The directions are hopeless....half the parts aren't even shown. :???: please help.
