I had an old pocket door separating my kitchen from the utility room. I usually keep it closed when washing or drying clothes to reduce the noise. I started using sticky notes on the door to remind me of things that I need to do before I leave the house.
Then I thought of a better idea. I went to Lowes and purchased a quart of Valspar Chalkboard paint and painted it. A few coats later it was done.
Now armed with chalk I have a "reminder door" to remind me !
Please see pictures - a) before, b) after painting, c) with a few reminders and d) a picture to show door partly tucked away.
