Beauty is in the eye of the beholder. I love it. To me it stands of the original purpose of quilting, to use left over fabric, old clothes. to make something from nothing. quilting used to be for the poor, to make something useable from something that otherwise the family had grown out of, or was too work, so the good portions of it were reused.
This reminds me of that. Your MIL should be proud to display it for all to see and get good use of it.
Too me it is beautiful. and it seems you are also starting to appreciate it's beauty. Hurray!!
