Back to joyannasmom and her messy sectional, where she frequently tosses her jacket.
Jackets should always go on a convenient coat rack or hook—not on the nearest chair! You've got three choices, really, on how to do this. Click on each type, below, to see an example or to purchase:
standing coat rack
mounted coat rack
over-the-door coat rack
There's no need to spend a lot of money, though there are some nice-looking ones out there if you're willing to pay the price. If none of the above types fill the bill, head to the nearest dime store and buy a nice-sized coat hook for just a few dollars. Install it in a convenient place—and then force yourself to use it until it becomes a habit.
Come back soon as we keep working through this mess!
