According to the calendar (but perhaps not the weather), Spring begins in a few days, which for many of us means spring cleaning and clearing out the clutter. If you’re helping a loved one downsize, or thinking about your own possessions, you’re probably trying to figure out a strategy for what should stay and what should go. There’s lots of advice available about what items have monetary value and what items you may want to save for the kids or grandkids. According to a recent article in Mental Floss, everything from old Boy Scout memorabilia to your Pyrex dishes could be worth a chunk of change and should be appraised before you heap them on a table at your tag sale. But those books and porcelain figurines that you want to pass down to the next generation? According to Elizabeth Stewart, in her recent Next Avenue article, your kids are not going to cheer when they hear you’re saving the silver for them. Stewart is an expert on these matters, having written the book No Thanks Mom: Top Ten Items Your Kids Do NOT Want. So read up on the expert advise, and set your strategy accordingly.
