I love Misty Fuse. I've had nothing but trouble with Wonder Under
(regardless of whether I read/follow instructions or not). Steam a
Seam is fine, but I still like Misty Fuse better. There is now a new
form of Misty Fuse that won't react to UV rays and so you can be
assured that it will never darken inside a project someday far in the
future when a careless heir leaves the quilt hanging in bright
sunlight.
