I had actually seen this technique before but never tried it. It was also fun to finally use the watercolors I purchased years ago. The rainbow was just a test to get the colors right and see how the salt looked. When it was dry, I decided to use it.
I like the sentiment, but it gets lost on the card. It goes in my 'to be fixed' box.
I am looking forward to trying the watercolor over salt technique soon.
