You will need a foam sheet, tracing paper, a picture or photo, a tag, crayons and watercolor paints.
First trace your picture. This can be a photo or a picture from a magazine. I used a photo of a rose. Don't worry about all the details in the picture, just try to get the general feeling.
Using watercolor paints, paint a background color. This will be the under pining of the tag. You can also use ink stamp pads for a different look.
Place the wet foam pad on the tag and print on the tag. See where you drew the lines, it remains the color of the tag.
Here are a few examples of printing with the foam sheet, depending on how much paint, you get lots of different looks. You can also use the foam sheet and print twice.
Next step is to take your crayons and put in some details. Don't worry about staying in the lines. LOL. I've shown three different amounts of crayon work from a few strokes to completely outlining the image.
Take your watercolor paints and using your picture as a reference and paint in some the image. Be free and easy, this is fun. This will be very impressionistic representation of your picture.
