Start writing notes on Christmas cards and get them ready to mail now. Odds are, nothing will change much between now and the middle of December. If you do a few of these each night before bed, it will allow you the luxury of spending more time thinking about and writing to the special people you rarely see but want to stay in touch with. It will also relieve the stress of one more last minute task.
Starting now will also give you a chance to include a small, flat item in the envelope, like a digital photo printout, a crocheted snowflake, a sprig of dried mint, or a coupon for something you know that person likes.
Here is a listing for tiny handmade tassels.
These only take a few minutes to make and do not require any special skills or talent. You could also add a long "tail" and make these into bookmarks.
