I love the replacement colors. Is this something he is to take back with him? They do have limited room when they return and regretfully things do disappear. If he leaves it at home, laundry won't be much of an issue later on.
As the mom of a soldier who has been deployed 3 times, I know this to be true.
It looks wonderful and since it is made with love, that is the only way it will ever be perfect...regardless of colors or skills.
Give him a huge hug and let him know we all do appreciate him and his honor.
