I found two summer knit dresses that I had looked for last July and when I couldn't find, I just figured I'd given them to Goodwill. Nope. I put them with the summer clothes so next year, I will know. But a fair amount of clothes did get into the Goodwill bag.
I ended up with two very full 13 gallon trash bags of trash and one full one for Goodwill.
Now shit isn't falling out of the closet and I have a much better idea of what I actually have in there.
The help of two cats made the process way more interesting. I am now totally exhausted and filthy and satisfied.
