If it's very thin, you could take about a third off the top.
Lyn, I took pieces off the privet hedge around my parents' home before they sold it, and planted them up for the flowers - I love them.
And yes, once everyone had a privet hedge, but trimming them became a chore, so they were grubbed out. Very sad to see.
