When I designed a trip around the world for a friend, I created a table in Word and filled in colors from the fill part. Can't explain it better, brain is fried. This way, I could rearrange colors easily (works also in excel but table comes already with squares) and wrote notes about what I did as I quilted that worked or didn't work and how to improve on the next trip wallhanging. I also sent this to my sister who wanted to see both apttern and notes regarding a trip quilt.
