Welcome, ShadowHawk! Hey, ShadowHawk Look at me, a newbie giving out advice...sign1 It's always good to hear from you, buddy! Did I mention I know your beautiful country?:mrgreen: About the tabs, yes, they're exactly what you've wirtten. Not using them increases significantly the quality of the model, but also the difficulty of building it as well, unfortunately. What do I do? Butt-joining, which consists of glueing the edges and holding them together until the glue holds. In places where I think the tension on the paper will be higher, I also apply some tape, but I did apply some "back tabs" (what you called "costum strips"). I have used all three techniques and combinations of them as well). You can find tutorials about this right here in Zealot (why bother to look somewhere else?).
