If you bought the Bazzill Swatch box way-back-when, you need to buy the updates. I find that when I have a piece of Bazzill that's older, and I really like the color, if I match it with the swatches I can usually find it in my local store, have them order it or find it on-line. It's so much easier to find when I know the name of the color! The updates are a must-have.
I don't know how any scrapper could live without these swatchbooks!
The Swatch Book has been very helpful in picking colors and knowing the name so I can order that just right color for any project. I intend to purchase more in the future.
