Step 2a had us to use watercolor over 3 of the coffee stained tags. I was surprised that the water color was so deep in color. Perhaps I was a little heavy handed. I used Loew-Cornell watercolor in tubes. I had bought a set of 12 quite a while ago. I just opened them this week. Anyway, on one tag I used lemon yellow with yellow ochre. On one tag it was cerulean blue with prussian blue. On one tag I used crimson with white. I didn't like the result so I topped it off with more crimson. I think I'm happy with them. I'll make a final determination when I see how the tags are used.
