I created another card today, this time using Kristina's idea of coloring on vellum.
I die cut the flowers and word from woodgrain cardstock, and was careful to get the stamp right. That's a little tricky with the texture. The vellum I colored in red, orange and yellow, but I am not at all happy with my results this time. I got several splotches of color on my woodgrain cardstock and managed to tear the vellum twice.
Now I'm glad it's done, but I don't think I'll ever send it. That's why I haven't created an envelop yet. I really should have bought more envelops at the trade show. They are really much nicer than any I've ever seen in a shop.
