all good suggestions,I also use Tite Bond II, not the III, it really doesn't sand well at all, and is for exterior const.

I would add I like to use a old credit card or plastic squeege to help line up the seams on the sheets,while using my thumb to press the pieces down to a flat surface like glass, so you dont have to sand the seam much at all and the piece ends up being nice and flat with hardly any noticable bump at the joint.

also if your stacking sheets, just place some wax paper between them and you can do several pieces in a session,I like to do the whole wing in a siitting prepping the balsa with the tape and then glueing them all up at once, just to get it done, I then let it sit overnight.

I also use a old CA bottle to apply the glue it works well, one thing is add the smallest bit of water to the glue just a couple of drops and it flows through the CA bottle better makes things easier
