I am far from an expert in this area, and this is really only the second time I've (we've) moved (I don't count college, because I could fit everything in my car). But after going through this, we definitely fell into a groove.
The most obvious part of packing are finding boxes. We had a bunch from the last time we moved, and we kept them in the attic, but I had no idea we would need as many as we did. I guess we HAVE doubled our family in the past 5 years! Our boxes filled a 10x10 storage unit (no furniture except some bookshelves). After quickly blowing through the cardboard boxes we had and using all the rubbermaid boxes we had, we decided to order some boxes. We jumped on U-haul's website and ordered $66 in boxes. After I clicked "submit order" I smacked my forehead. WHY DIDN'T WE ASK PEOPLE ON FACEBOOK!? We received a TON of ideas, and between our friends who run the local Little Caesars, to a convenience store owner, and someone who works at the poultry farm (those boxes were brand new- no ick factor there) we were able to round up plenty.
Also conveniently the week that we needed newspaper to wrap fragile stuff in was the week my newspaper membership ran out. Obviously I'm not renewing since we are moving, but it would have been nice to have that. Instead I turned to our closets. Josh had started packing his clothes and they quickly began filling up a big box. I started grabbing T-shirts to wrap platters, dishes, and glasses. They worked like a charm! And we were able to completely empty the box so we had an extra box to pack stuff in!
We kept a plethora of boxes in our attic of things that still have warranties. Although some of the boxes were used to house their original items (my sewing machine, stand mixer, and Silhouette), most weren't going to be used for that. So we used them to pack other things! We'll still be able to keep the boxes with the warranties, and they double as packing space.
The corners of my house served the biggest purpose in this whole process. I had a corner for yard sale things, a corner for consignment things, a corner of stuff we were actively packing, and a corner of things going to my parents house. We'll move in with them for a little bit so I had to think through-- "Will I use this in the next month" with every.single.item I packed. But sectioning off everything helped me keep my sanity.
This was my pile that was going to my parent's house:
Yard sale stuff went in another corner by the front door:
attic storage that I ripped off from Michelle Duggar.
As I packed the boxes, I wrote the general contents on a card. I didn't write everything, just the major things.
