I think you're missing the point, Leon.

Edges do not have to be parallel to glue up flat without gaps, they just
need to be complementary angles that equal 180 degrees.

;~) No, I got your point Swingman.. and, you did make a good point and or
tip.... I think I probably did not explain why glueing up non parallel
boards is "not always" OK. I build a lot of furniture with contrasting
color woods. Very often the tops will have multiple color woods around the
perimeter. With glued up pieces of contransting wood for these borders and
these being 45ed in the corners the individual pieces must absolutely have
parallel edges or they will not lighn up properly at the joints.
