My husband has the worst memory in the world! Sam says he has a hole at the bottom of his head and things fall out. After almost 10 years of marriage I'm used to it but sometimes things are important and he needs to remember them. So for his birthday I made him this 'remember bag'. It has a pocket at the bottom for items to remember like letters to post, a pen pocket and a little pocket with post it notes clipped to it for things to remember that won't fit in the pocket like take milk to work. It's hung on our back door which we use as our main door and when I need him to remember something I put his car keys in the pocket so he knows to check for what he has to remember.
Here is a picture of it ready to be wrapped for his present.
And here it is in use on the back door with his keys in the pocket and his list on the post it note.
