This is the technique that I was taught by Harriet Hargrave. I usually only do with with fabric that I feel might be a bleeder. I never pre-wash. I always use color catchers and never have had a problem. I would use Hobbs 80/20 instead of W&N. It is a bit fluffier and not give you the flat look at W&N will give the look of the quilt.
