You did a beautiful job on this - can't believe it is your first quilt. The piece work and the quilting are amazing. Not everyone reacts the way we expect them to. Just know that you did this with love.
Don't let it stop you from quilting either. The next one you give away may be met with tears of joy. I've had quilt gifts barely acknowledged and others that I know are used and displayed with love. Interesting for me, it is the boys and young men I have gifted that seem to appreciate the quilts the most. The girls/women/men mostly don't understand why you wouldn't just buy a comforter at the store.
