Great tips! I've been trying to spend more time cleaning and tidying, because I find myself less stressed in a cleaner house. In fact, I got so inspired I'm renovating our house and plan to clean each room until it is cleaner-than-new - our unfinished house was kind of grubby when we moved in, and has stayed that way.
I'm very not good at putting craft supplies away after use. That is one of my worst faults.
