I had that happen to me as well when I gifted a twin quilt..she opened the box, said "it's a quilt" "thank You"
then was going to past it to the side without opening the quilt and showing it....well, I opened my mouth and told her to open up the quilt so that she could see it....she did...and everyone else oohhhhed and awwwed...
she not so much..
oh well I had fun making it and the guest enjoyed looking at it...
