packing and storing, any tips?

A mommy blogger is up to her elbows in detergent, septic tank cleaner and vacuum bags to clean up her home for an impending visit from her sister whom she hasn’t seen in years. She says her house is overrun with bags of her children’s old clothes. I suggested she might also use those big green garbage bags which are what I use. The trick is to press down on the clothes to squeeze out all the air so the package will be smaller and take up less storage space. Do you have any tips to share on how to put away clutter which you can’t part with, yet :wink: ?
