Mine isn't exactly a September challenge but when we moved in July we knew already in June that it was going to happen so we did a major purge. We had a family room that we used as the "study". There were four desks in that room with a treadmill, a fireplace, a rocking chair, shelves full of reference books, encyclopedias, printers, etc.
As part of the move we realized the kids were no longer using that room anymore since they all had laptops and were only using the printers to print things. We sold/gave away all but one of the desks and recycled one old computer. We took only only one small desk with us and the desktop computers (2). We went through all the linens and shelves throughout the entire house and purged so much stuff so that the rest could fit in our new-to-us smaller but older home. It was a hard purge but necessary and even kind of cleansing to do this.
I really don't have any more things to purge but I'm not going to buy anything new either. We vowed to one another we would be careful that we don't become attached to possessions like we seemed to be in our country home. There were so many unnecessary things that were hoarded because we had the space to hoard them! We even felt like we were irresponsible to God in that we didn't honor Him in the things He gave us. It really gives us a new mindset as we move forward.
