I second what feline fanatic said. While I am a Christian and cherish the meaning of the cross, I don't wear crosses because it was an instrument of torture. But I'm not offended when others do because they are proclaiming their love for Jesus, I believe. By the same token, we don't decorate our home with a cross anywhere. I have Jewish ancestors who suffered in the Holocaust, and some died, so I despise even the quilt block that looks like a swastika. I know it's not supposed to be that, but since it resembles it, it makes me cringe.
I would not personally be offended by fabric displaying the cross or menorah. I've made Hanukkah gifts with menorah fabric, but haven't made anything with cross fabric. I'm not easily offended, but I am easily saddened, if that makes sense.
