I am in the process of doing the same thing. I promised one of my nieces a black and red quilt and now that I am half way through it I know I am not going to be able to let it go. It is my first French Braid and it is coming out beautifully. I will have enough fabric left over to make a D9P so that is what I am going to make for her. I am not usually this way either and I am not particularly fond of black and red but for some reason I really love this quilt. Don't feel guilty, some quilts just call to us. Make her another one with lots of love and it will be better for both of you.
