Hi, i just installed some crown molding in a room very long piece
25-35 feet. I had to cut it in two pieces.. The smaller piece where I
cut it is like 2 feet... But when I join it, (like a puzzle piece)
there is a pretty big gap there. Quite obvious, even when I paint it
it will show, what should I do???

Fill the gap with canned/aerosol foam, let set, trim off & fill with
(say plaster?)
