Wow, I love this! How did you quilt it together? Were they all individually pieced together, or was it one big material in which you stitched around the colors? Regardless, it's beautiful.I think as far as the 3D effect, I would do some embroidery stitches on just certain tones - maybe on your scarf or across the body, just to single out the person in the piece.
It was one big piece of cotton on which I printed with a commercial printer, then added a piece of flannel in between and backed it up with cotton. Was kind of difficult to get the needle thru. I just did small areas at a time.Kind of fun.Embroidery stitches - great idea, will see what I remember and can do
