no i'm not offended, it means i didn't give them a gift that suits their taste, style, or lifestyle.
its not their fault, its mine for not putting more thought into their gift.
they are grateful for the gift and i always get a thank you and more often then not a thank you card but if it doesn't get hung or used then i know i went wrong some where along the line.
i typically ask them but i also have very up front relationships with the people i give quilts to and can ask for truthful feedback because i don't want to make something wrong for them again or give them a quilt at all if they don't like them.
i'm an artist and all my friends are artists so we understand critique and don't take it personal.
if you have an open relationship with these people you might just ask them whats up and ask that they tell you the truth but that means not getting upset if you don't like their answers.
