…I have started ordering washi tape!
I usually block off public holidays in my calendar with washi tape so that I know not to book lessons then, and also remind myself that 10-week courses will finish later if there are public holidays during their duration.
I also put a small piece of tape on birthdays and anniversaries so that I can remember them.
I have been using tape in my Hobonichi Weeks as well – along the bottom of pages and demarcating certain categories.
I ordered a couple of rolls from a local hobby store and it is quite nice to look at the cheerful colours in my calendar. I guess during these gloomy times, we need all the cheer we can get.
