Recently, I came across a pitfall of the color card when I was trying to build a color palette for a new project. Because the swatches are glued down to super thick paper stock, it's nearly impossible to get a good comparison of colors that aren't side by side. The only solution was to cut the whole thing up!
I ended up using a leather hole punch and an old ball chain to make a swatch ring. If you don't have a ball chain lying around, you can find them in craft stores and hardware stores for pretty cheap. You could also use a regular hole punch, but I wanted smaller holes in my swatches.
I cut my swatches into rows and hole punched each row before cutting them up. I made sure to do everything one row at a time to keep it all in color order as I strung the swatches onto the chain. Now I can make easy side by side comparisons without making a mess!
