Good luck on the quilt. I sincerely hope you enjoy making the quilt and I sincerely hope she likes it also. I understand you are making it with very good intentions. Perhaps she will receive it in the spirit that it is given. Please let us know how things turn out.
I have a relative that would not use a hand made quilt if it was the wrong style or color to match her decorating unless the weather turned very cold and the furnace malfunctioned. So of course I would not put my time into the wrong style and color because it would be useless.
