I too "inherited" quite a lot of thimbleberries fabrics. Lately it has occurred to me to use them in place of civil war fabrics as those are usually quite dark. I found a Thimbleberries book at a thrift store and have made (1) quilt from the book and intend to make others as well. So my suggestion is look at civil war patterns, and I think the log cabin suggestion is a good one as well.
