A Memorial quilt is a great idea and I can tell you're thinking big! One of my first quilting projects was making small (7"x7") mini-quilts out of my mother-in-law's clothing. I was just starting to quilt, so it was a log cabin design. I made enough for everyone in my husband's generation and the grandkids. I hung each on a miniature hanger with the small craft clothespins. I stitched a heart somewhere on each and used a few of her old vintage buttons on each quilt. Everyone was delighted. You might think about using your leftover fabrics for something like these to share your love!
