I thought I had posted this last week, but can't seem to locate the message. So, if you've seen it before, don't think I'm trying to brag or repost my own stuff
I started with several charts of data that others had posted, and I cross-referenced all the Twinkling H2O item #s with their colors, then added (from another SCS stamper) the coordinating SU! colors.
If you're interested, here's the data in a spreadsheet. It helped me determine which sets to order when I compared to the SU! colors I already had.
Enjoy!
