just because he loves zombies doesn't mean you have to make a wedding present of them unless the new DIL also loves them. I like zombies too but even I don't think I would do zombies for a wedding present.
make them a Beautiful quilt. They must have other interests, maybe nascar.
save the zombie stuff for a birthday.
Another way to look at is loving a foot ball team. I still wouldn't want a WEDDING QUILT with a logo on it.
people can like whatever they want. I love french fries but I don't want a quilt or even a mug with a potato on it. but that's just me!
peace and may the wedding be wonderful and the couple make a happy life together.
