K.K.
This is something we usually do for weddings, but I think would be a good house warming gift. It is a part out of the movie "It's a Wonderful Life", where they take a family to their new home. You put the movie, a bottle of wine, a loaf of bread(we use french), and a thing of salt with this saying in a basket. (We add other stuff for weddings when we have more to spend...like cloth napkins, wine glasses, gift cards, etc.)
The line from the movie is "Bread-that this house may never know hunger. Salt-that life may always have flavor. Wine-that joy and prosperity may reign forever!"
This has always been a hit with us! Have fun!
