The thought of embroidering some of your mom's quotes on sashings between her quilt blocks is a neat one. My mom has been gone since 1999, and one of my sisters (also a quilter) has taken a notebook and writes down "momisms" - things Mom used to say frequently as we were growing up.
Your mom's legacy to you is beautiful! Whatever you do with them - keep them as block or make into a quilt - they are priceless!
