Here's my WFMW tip....and thanks to We Are That Family for the Linky Party!
We have a very handy set of hooks hanging on the wall next to our garage door. When I have an item (book, toy, etc.) I need to pass on to a friend or return to the store, I place it in a grocery sack and hang it on a hook. There is one little problem-o with this system. I can't see what's in the bag to know where it needs to go.
So I grabbed one of my new little organizers from Ikea and threw in a stapler, some note cards, and a sharpie. Now when I put the item to be returned in the bag, I label the outside using the cards.
Now I know exactly what needs to go where and the cards are a reminder that something needs to be taken with me. Problem-o solved!
