Hi...thanks to everyone for your thoughts. It is true that the points are what is challenging because of the right side being shorter and to find that yellow would be kind of impossible. Even putting points on the other side.... which I am not an expert on fitting things in like that....would make it uneven. And yes, the quilting on the left side is different and it looks like the piece was cut from something longer.
I am doing it as a favor not getting paid which is fine as I would like to help her. I will email her and ask for her thoughts as some of you had mentioned.
Again, thanks, you have given me some clearer ideas. I like the pillow idea.
