I came across this site as I was surfing today. It's for a free software download called Quilt Assist.
http://www.cosman.nl/software_en.html here's the software description
"QuiltAssistant is free design-software that can help you to turn your photos into quilts. Rather than the traditional approach of breaking up the photo into little squares ('watercolor style') it allows you to divide the photo into pieces of arbitrary size and shape.
On completing your design, you can print templates including seam allowances.
A picture is worth a thousand words:"
I haven't downloaded yet as my computer is being stupid arrrg, but hope to download soon
