Hymn of Thanksgiving

I've been instructed to use a "hymn of thanksgiving" in addition to the Communion proper. In the past, I have tried to use something Eucharistic here, but with Worship III, I feel like I'm kind of limited in terms of not using the same ones over and over. Maybe I'm not being creative enough!

I could also set some other hymns (not in WIII) in Finale and provide those to the congregation.

What works well for you and contributes to the ethos that we're trying to promote?

Thanks, everyone :-)
