Christmas Eve is 7 weeks from today.  Preparing gets serious once the calendar turns to November:

• If you have any presents that must ship overseas, you need to buy them this week so they can ship before November 15th.
• Take stock of your cooking and baking supplies.  Do you have enough cookie sheets?  Storage tins?  What cooking and baking basics do you have on hand:  broth, flour, nuts, sugar, vanilla, almond extract, spices, baking powder, colored sugars, etc.?
• Take stock of your Christmas cards.  If you bought them in the after-Christmas sales last year, find them.  Make sure you have enough. Also, check your stock of address labels.  Holiday stamps are available at the post office, so you can pick them up at your convenience.
• Take stock of your wrapping supplies: paper, boxes, tissue, tape, ribbons, bows, and gift tags.
• Take stock of your decorations so you'll know if anything needs to be repaired or replaced.
• Begin placing online orders for gifts.  If there's a back order, you want there to be plenty of time.
• If you find yourself with a few minutes of an evening, start addressing your cards.  When you only do 10 or so a night, they stop being a chore and start being a joy.
