I want to use some leftover maple, cherry, or oak g2s particle core to veneer over a custom veneer piece (~20 x 26) My question is does grain direction matter. The veneer is some kind of burl or quilted pattern. this inside piece will be bordered by a banding (quartered) that is perpendicular to the quilted piece along each 4 edges. Or should I consider buying PC or mdf? I really wanted to do this today if anyone is out there.

Its generally advised to run perpendicular to the veneer underneath. If it was me I would probably cross band it, just to be safe.

It is always recommended to veneer in similar fashion both sides of a core, a single layer on each side, a two ply on each side, or a 3 ply on each side. And if I were applying new veneer to a core that already has veneer on both surfaces (most likely with the same grain direction on each side) I would orient the grain direction of the new piece perpendicular to the existing surfaces. And if going to the trouble to make a face assembly with a field and quartered veneer around the edges, I would make a two ply because of the multiple pieces of veneer and multiple grain directions. In some (many?) situations that might be overly cautious, but the additional time and materials cost is less than the time and trouble to perhaps have to re-do the panel.
