I don't think you are being sensitive, but I wonder if she thought it was store bought. It does look perfect, after all!
That happened to me once and later the recipient said "You MADE that?" LOL! It was a nice compliment, although kind of backhanded.
Perhaps she will later realize and let you know how much she appreciates it. You did a fabulous job with the fabric choices. The quilt is just adorable! Pat
