Your quilt looks great so far! I love bargellos, they're my favorite quilt to make. I hope you'll post pics when you're done!
I tried playing with that software before but it didn't want to load properly for me, I think my operating system was too new for them at that time. That was a year or so ago, though - maybe they've updated it since. Thanks for the link - I'll try it again. My laptop is "old", now!
