I'm guessing it's at least partly because the world has gone crazy. We can't count on our culture for civility or kindness or gentleness - you watch the sitcoms and every "joke" is either an innuendo or a put-down of another character. We don't go to church and build church families. We don't know our neighbors. Strangers take up arms and shoot up banks or schools or movie theaters.
A quilt is from a time when the world was slower and sweeter and less filled with ugliness. It's gentle and soft and comforting. Maybe those easier days can come back, again.
