For your friend's quilt you could use polar fleece. It is very soft & warm and the quilt is light in weight. I use it for little kids quilts and have no problems with quilting it.
I keep the quilting simple and to a minimum ( no stippling or such) I wasn't sure the first time I used it but it was a dream to use. For a pretty quilt could you buy cream or a pale color.
We can get those colors here in Australia so I expect you could get them in your corner of the world.
For the camo try an army disposal store. You never know what you may find.
