Shalom! Post a picture of the quilt, without it we couldn't hardly give you any meaningful ideas. There are quite a few folks here on the board that are outstanding quilters with a big bag of tricks!
Another idea is to visit Leah Day's website. She has video's of lots (over a hundred now I think) of different quilting motifs - mostly fillers, but others as well.

We would LOVE to see a picture of that quilt though!!
