I echo the thoughts of b.zang on this question! My experience in this type of situation says dont make it complicated, or ask if they want one, or colors, etc. This is a gift from your HEART so i say just go with whatever your heart says to do! Your neighbor sounds like such a thoughtful young man. Who knows, like somebody said maybe his wife is just shy or has trouble interacting with people in general. Your heart says you want to make them a baby quilt so why not? Im sure it will be a BEAUTIFUL GIFT OF LOVE!
