I ask for help 10 days ago and you all came through. So I'm asking for suggestions now. I measured this lap quilt and it is 51" square. Is that going to be big enough for an 8 year old, or should I add some more border to make it 55" or even 60"? And I've been thinking about the color fabric for binding..... what do you all think about black to kind of finish it all off?
