I suggested that. I may have neglected to say that I rubbed the foil
rather aggressively to smooth it out on the board. That has worked
for me.

What did not work was folding the foil over, since if it wrinkles, it
tends to destroy the traces under the wrinkle.

Not sure why it didn't work for you, but if you get good results and
no wrinkling, then keep to it. I'll keep on not folding the foil
under as long as it keeps working for me.
