My MIL was a prolific charity quilter. When she passed, her church wanted us to have a couple of the quilts she had made that year, since the quilts were for comfort and we were in need right then. So we kept those quilts, since they meant a lot to us. I had even helped her with design on both, since she always had a quilt out for design "help". Anyway.
In return, I made a quilt of my own for the church donations. My plan is to make 2, but haven't decided what to do for the next one.
So if you like the quilts, keep them. If you feel you need to make a quilt for charity, make one yourself. Her quilts will have more sentimental value to you than to the charity recipient, but the charity recipient will still get a quilt.
And I also like the idea of finishing one of the quilts for her husband. But you may not even need to do that, because I'll bet he already has some of her quilts that she specifically made for him.
Good luck!
