You might consider a simple four patch (or nine patch) with red sashing and/or binding, perhaps adding some blue chambray blocks to give a bit of relief from so many patterns in the fabric. It would also be nice to add a photo on fabric with Grand-dad on the back. I would think she'd be happy with a sofa or lap quilt. Or is that the same? My quilting bee used a lot of shirts from a resale shop to make lap-sized quilts for veterans. They looked like they came from an upscale catalog.
