Make sure you have an extra roll of packing tape, extra packing paper and extra moving boxes. Great free box sources that I have used include Chick-fil-a Waffle Fry Boxes (very sturdy and perfect "moving" size), Avon boxes (with the lid - oh these are the BOMB!), and boxes from the Liquor store. The little wine bottle inserts are great for keeping your glassware safe or creating little cubbies to manage packing small stuff.
Buy LOTS of Magic Erasers! These bad boys are fantastic for buffing out scratches and scuffs on your walls. Also, assess your cleaning supplies to see if you need some extra to use on your post move clean out. (No one offered to give me anything to say that - I just love em!)
Don't put it in the box if you aren't going to use it when you unpack it. Start a Goodwill box that you can toss that stuff in as you go.
Invest in some decent disposable plates, bowls, cups and flatware to use once you packed up your regular kitchen dishes. I also pickup a couple quick microwave meals to cook those last couple nights to ease your prep and clean up while you are taping up boxes.
Pack a "open me" first box. Mine includes the following
- Coffee pot and coffee (Priorities people!)
- A mug (Yep - made that mistake ONCE.)
- Trash bags
- A shower curtain liner, set of towels, and a bath mat
- Toilet Paper
- A roll of paper towels
- A set of sheets and a blanket
- Food bowels for the pets
- Basic toiletries
Use your luggage to pack your clothes! Don't ever move luggage empty - that is a huge waste of easily rollable space! Also pack things in trash cans and laundry baskets.
Scope out your rooms before the move and ensure you have a lamp ready for any room that doesn't have an overhead light.
Try to plan your move so you have time built in at the end to be able to clean your old place. I like to plan a weekend to move and a weekend to clean.
