If she really wants it larger, suggest that you could attach a bed skirt to it (she could either purchase a ready made skirt that you could use, or coordinating fabric that could be ruffled/ stitched onto it). I made a bedspread this way and it looked great (quilted top with ruffled sides). If you are lifetime friends, I am sure that you want to do something...but if you really don't have the time or desire, this shouldn't ruin your friendship. You were a gem to do what you already did for her.
