Rogerio, your gluing technique really interests me. What is the name of this glue you are using. You have excellent building skill, but I can see that this glue is also working very well.
Thank you for the "excellent building skill", but I think I'm far from that... :cry: I guess I'm improving, anyway...

This is the usual edge-glueing (some people say butt-glueing, and no tabs)
About the glue: it's same old PVA + alcohol, although it MUST be in different proportions, for it's stronger than the styrofoam glue I was using, and makes less of a mess.
You'll see in the label that it says "Cola Arte Fix" = "Glue Art Fix" (that was easy!

), "Não mancha - incolor" = "Doesn't stain - colorless", "Não enruga o papel" = "Doesn't wrinkle the paper", and last, but NOT LEAST, "Especial para trabalhos artísticos e fotográficos" = "special for artistic and photographic works". That's exactly why I bought it, tested it, and will stick to it (pun intended

).
The glue's brand is HERO and its manufactured in a nearby city from Rio. Take a look at its pic, please.
