I'm sorry for all the loss and potential loss you and your wife will experience. Mom Allen will appreciate your kindness very much, I'm sure. The quilting looks like many hearts, that will reach around her and cover her in your warmth and love.
Love the way the green center block just pops! I've recently made a light/dark blue log cabin and let me tell you the center was just there...not popping or anything. What a difference adding a splash of color does! Like it!
