I glued the color swatch and the color name/number to one side of the clothespin. On the back side I indicated the room and paint brand, along with a magnet piece left over from another project. I added some buttons just for fun.
These will go up on my fridge so I never lose them again. And when I want to have the color with me when I shop for accessories I can just grab the clothespin and go. This will work. That is ... until I decide to repaint and change everything!
