great home decor idea! Take popsicle sticks and paint them the color of every wall in your house. Carry with you on the go to match furniture, curtains, decorations, etc. I've seen the full paint stirrer version of this but love this portable-sized idea!
I would try to incorporate fabric swatches too. My purse is big enough anyway. Pocket sized floor plans to carry with you when buying furniture, accessories ,etc. that have dimensions and paint swatches on
Never forget your paint color! On the inside of your light switch or outlet cover, using a permanent marker, write the paint brand, color name, swatch number on a piece of painter's tape for quick reference. Change the room color? Change the info tape!
