Darlin' when my mil was alive I would make her homemade things. I made her two pillows that I worked very hard on, a sampler poem about her son in cross-stitch that took me almost a year to do and frame and several other things. I found them in her yard sale one year!!! I bought the sampler and hung it in my stairwell next to a picture of her and my husband. Sometimes people just do not love what you love frankly and you have to just accept it even as heartless, cruel, or selfish as you find it. Like others have said, if you make her more, use cheap yarn, but I am not sure I would. I would buy her a pair of slippers and tell her you don't have time at the moment but wanted her to have something for her feet.
