The most "throw-up-my-hands" moment so far in the storage unit purge has got to be the boxes of other, empty, "perfectly good boxes" I've uncovered and recycled. We've been paying to warehouse a remarkable collection of empty space. (I'm pretty confident I haven't inadvertently destroyed anyone's gift of 'the breath from their body' or the like.)
I will be putting the vintage stuff up for sale on Etsy, in particular the Nativity sets and the glassware. There's a major donation run for the clothes in my future as well.
I'm making better progress that it seems if I measure by boxes emptied. Even when I omit the ones that were already empty when I started.
