Some time back I wanted to do a portrait in a quilt and I remember reading that one way would be to project the picture onto a design board and then to 'pixalate' it showing all the different areas and colors to use. I think there are simpler ways of doing that nowadays with computers but I lack the technical know-how. Maybe someone (what am i saying maybe?) here knows how to do that and can explain it. Good luck. Let us see you finished project.
