A few ideas for imagery:
- St. Mary but be subtle about that if you use.
- Angels or Angel wings but don't be generic.
- The picture of their church on their Facebook but cleaner/simpler we need a logo we can use on shirts, print & web.
- They have a community garden, so a garden incorporated subtly wouldn't be fine.
I'm uploading 3 photos we like the general feel of. If you are in this ballpark you are doing it right! :D
