You've most likely packed up belongings for a move, so you will understand how the first part of this process works: you gather as many clean, sturdy boxes as you need.
Now here's where it gets tricky. You'll be packing up many kitchen items and not unpacking them for a few months. So you'll have to find storage space in your home or somewhere else. Also, make sure to pack up (or move) fragile items that are near or hung on the walls adjacent to the kitchen. Construction-induced vibrations during the remodel could damage these items.
You should decide which items might need to be unpacked during the remodeling process. You'll want to keep these items near the top of your boxes. Also, it's a good idea to label your boxes to make it easier to find these items.
You'll want to complete your packing before the remodel starts, and its advisable not to wait to the last minute. Of course, this means setting up your temporary kitchen before the remodel, which requires additional planning. If the start of your remodel gets delayed a few days — which isn't unlikely — resist the urge to unpack your kitchen items. There's no point in hitting the snooze button on your temporary kitchen. You'll need to get used to it sooner rather than later.
