My MIL has been gone for many years now. I adored her and I think she loved me more than her own kids. If I had quilted then and made something for her, she would have treasured it. I don't know what your MIL is like, but if she were like mine it would have hurt her immensely to know that I felt something I made was not good enough. I have a queen size crocheted bedspread from her. It is very heavy and mostly WHITE so I don't use it very much, but it is so very important to me because she spent many hours rocking and crocheting it for me.
Just something to think about...
