Hi ladies

So my fiancé and I just opened registries at BB&B and Macys. We don't have a home yet.... so how do you register for things like bathroom towels and oven mits when we have no idea what our home will look like?? Should we just not register for these things? I can assume what colors I will be using...but my fiancé keeps saying that "we don't know till we have a house." Should I just pick a color scheme and go?
what should I do ladies?
