Nowdays most publishers print things like barrels on normal paper (soft one like that one for printers), older one (especialy Maly modelarz) got fuzzy tough paper wich is almost unable to roll smoothly only wtering and hours of rolling on pencils toothpics, old radio antenas can give good results. And there is another question than...why you are building models from home prints when u got acces to printed releases? (Maybe it is quite strange for me cause printing cost in Poland are to high for me?) Is it only matter of scale? or costs of buying those printed models from publishers?
