The quilt is beautiful. I would be affraid to wash it without doing a spot check on the sashing with cold water and a clean white wash cloth to see if the color will run. It it doesn't then I would use a gentle detergent with cold water in a gentle cycle but I would also stay at the machine during the 1st cycle incase you see bleeding and need to immediately remove the quilt. A suggestion is to always prewash your material with like colors or on their own if you think they may run that way you will know ahead of time if it will have color runs after the quilt is made and washed.
