Key storage for a deep purse... I went to a dollar stare and bought a (?) lanyard. I don't know if that is what they are called, but it is a long strap that is a loop, like a necklace and it has one of those closed hooks at the end where the necklace (?) closes. I looped it around the strap of my purse and it has stayed there ever since. (Many, many years) It is black and the purse is a very dark brown leather, so it almost matches. They had numerous other colours, but I didn't need bright pink or baby blue. I did go back and get one with Canadian flags on it for when I travel. I used to have suitcase keys on it, but now suitcases tend to lock with combination locks. IF I need to put the keys into my purse, I hook them onto this closed hook thing and I can toss them in and let them sink to the bottom because I can just yank on the top part around the handle. Usually, if I don't have my purse, I have gotten into the habit of keeping anything for dh (cell phone and his truck key that is attached to my car key) in my right pocket, because he is my right hand man. My cell phone and my house keys go in my left pocket. Sometimes it is the pockets of my housecoat, and other times it's a sweater or jacket.
Something I have been learning towards the end of every month is budgeting for books. I quickly count how much cash I have on me before I go out and when I am out book hunting, I know how many books I can get. I spent close to $20 today. Part of that was a 13 book series on all types of gardening for $4! They weren't exactly new, but the basics of gardening and looking after house plants, etc, hasn't really changed much since the 80's.
