This fabric is your neutral...........I would add any medium or darker fabric.......e.g. a colonial red, forest green, medium to dark purple, even a darker brown or rust............there are man patterns out there for 2 color quilts...........
I might use this as background fabric for a four patch or nine patch, and find fat quarters or scraps in colonial, civil war type fabrics (darker, duller colors, blues, reds, greens and browns)..........It sure would make up a beautiful quilt, and I don't think there is anything easier than a 4 patch or 9 patch bock.........
Nancy's Notions current catalog has a book or book with DVD on making the old quilt patterns with modern conveniences (like rotary cutters)............You might want to check that out on-line......
Beautiful fabric! I am sure whatever you make will be wonderful!
