Liquor stores have the best boxes and the clerks hate having to break them down. Go to the local liquor store and ask them for boxes. You'll get all you need.
Another good trick. Instead of packing delicates like plates with paper, use clean clothes. T-shirts will keep things from breaking and you cut down on the number of boxes.
If you need it you will find it, and if you don't, maybe it is unncessary clutter in your life that would be better to get rid off in a yard sale asap?
Also agreed. OP is going to find they're spending more time setting up some system, entering data, and stopping to use it instead of just putting everything in a box labeled "kitchen" and unpacking it in the kitchen when they get to the new place.
I support this idea. Moving is the perfect opportunity to classify your stuff into useful and wasteful, specially clothes, shoes, and some older electronics. Recycle and donate.
Also, if you have a phone you can turn any document into a digital one, find manuals online and trash the paper ones, etc.
It's amazing when you suddenly feel lighter, and you didn't know you had all that psychological weight on you.
I doubt you need more than a notepad app. It's what I used the last two times I had to move between countries and it was more than enough for me and customs. I simply wrote down important stuff as I put them in numbered boxes.
Spreadsheet are overkill, a note app is easy to access on your phone at all time and can be easily shared with someone.
Here's a sample of what I ended up with:
15 - camera stands / shoemaking tools / notepads / trophies / guitar cable / weaved basket X2 / cooler bag / curtain rings X 3 /
Sketch up or an easy cad program so you can easily measure your stuff and the rooms to find ways to fit your furniture. I used sketch up when I moved and just a top down 2d quick line drawing of our house. Then measured our furniture as objects and moved them around to see where we could fit and what direction to put our bed etc
I'm not sure. I only recently switched to Linux and was thinking of trying ondsel but haven't really looked into it further. But I also still have a windows vm on my server with sketchup 2017 in case I need to do anything with that to convert my sketch up projects
