I use the Behr paint chips from Home Depot because they seem to have a little more surface area and a convenient hole to link them together. Once I emboss them I lightly sand the painted surface so that the design shows through easily.
I keep this swatch book in my craft tool box so that I always have them in arms reach when I am working on a project and can easily see which design will best suit my project.
Since my collection is relatively small compared to most of you out there, I am able to keep my embossing folders in a small basket.
Paint Note: I like the Behr paint colours and have fallen in love with the CIL Smart Paint, it has silicone in it and goes on creamy smooth and is incredibly tough. (former Benjamin Moore painter) Home Depot can colour match the Behr colours for the CIL Smart Paint.
