They ended up being a little different than what I originally planned - but at this point, I don't know if I even remember what I originally planned!
I also made little gift tags that said "Happy Holidays from My House to Yours" and attached them to the key chain with plain old-fashioned string. I began house distribution today in hopes I get them all delivered - whether in person or US mail - by Christmas. I have a feeling that the US mail ones will be a little late (haven't addressed or mailed them yet!).
Houses, houses, and more houses! Happy Home Holidays!
