My local Home Depot only had circular trays with casters, and for some reason, I decided the ones I needed should be square. Fortunately, the internet (Amazon) provided me with the exact ones I was looking for and delivered them to me, along with zip ties, two days later.
What we do a little differently with our calendar, is that we have event tickets (that we previously plan, obviously) favorite holiday movies and tv episodes, and activities like baking gingerbread or making a holiday charcuterie board – instead of the standard small gifts and candy every day. We do hide candy on random days, and for special occasions there are gifts (for instance, two years ago we went out of town for a few days and so Chad got a new pair of wireless headphones to take on the plane instead of making him wait until Christmas day to open them). However, it is more of an event calendar than a gift calendar.
The most important factor in the magic number AND capsule wardrobe is that everything you own, when washed, needs to fit in the space you have. If you have drawers fit to bursting, you can’t put anything away. Once you’ve pared down to what you need, make sure everything has a place where it fits. Each individual system will look different, but knowing what you have, what you need, and what fits (in your closet and your life), is a major step in getting the piles of laundry under control.
