Here are a couple of cards that I made that incorporate my trying to make more birthday cards as well as cards that don't use too many embellishments. However, these still use paper piecing so that they weren't too plain! I stamped a couple of the image on different patterned papers then cut them out and swapped some of the pieces to get two opposite coloured images. The hair, mouth and shoes are coloured using my SU pastels and blender pens.
