OMGZ, I so know how you guys feel. When we first moved in, my husband thought it would be nice to do a nautical/lighthouse theme in the kitchen. I thought "Okay, that would be nice", but I wanted to stick to more vintage, real seashells/driftwood, antique maps, etc.
Now, whenever someone goes to the beach, they ALWAYS bring me back little cheap trinkets from those giftshops.
I have not one... not two... but THREE lighthouse-shaped cookie jars. THREE, PEOPLE!!!
Ah, well... whatcha gonna do? I just smile... put it on "display" for a couple weeks then goodwill it. It used to bother me, but now, I've realized that my house is just that- MY house. It's where I live 24.7, so I'm going to have it the way I want it.
