If I had to pick a favorite technique, it would be watercoloring. I love doing it, and I love the soft look of the finished image.
I made this card quite a while ago, but as I was going through some of my old image files, came across it. Unfortunately, I can't remember the name of the stamp set, and I'm too lazy to go look it up. :)
The image was stamped on watercolor paper using Staz-On ink. This is really the best combination for watercoloring, but if you aren't going to be applying too much water, you can use some of the naturals papers too.
I'm really glad it's spring now and not fall, but I have to say, that this image does make me hungry for some fresh fall apples...and apple crisp, and apple pie....:) Have a great day!
