Placemat suggestions

I haven't been here in a while. Got a part-time job that is seriously cutting into my quilting time! I have to make several sets of placemats for a church event and find myself stumped as to ideas for something simple, yet attractive. I don't have a lot of time and don't really want to work with lots of pieces (i.e. half-square triangles for star points). I'd like to just use some really "now" fabric colors and let the fabric be the focus. Any good ideas?? Thanks so much...NancyH
