What an opportunity you have. You are starting with something beautiful that you love and there is no better beginning. You could make a new design that is all your own. My first thought was something like a crazy quilt with all that beautiful stitching to add more texture than just the pins. In my mind's eye, I see a crazy quilt with satins and velvets stitched together around a center reserved to show off each of your brooches. A crazy quilt could even display those family heirloom hankies. Let us know what you come up with, it's definitely going to be exciting to see what you decide.
