venieer repair piano

I have my uncles grand piano in need of repairs. The veneer was broken off in a move a few years back so there isn't a broken piece to use. He suggested using a piece from underneath to match but i thought i might check with some experts first. I don't have much experience with veneer. So any tips appreciated.
