I love this product. As I like the feel of new fabric I don't usually pre wash before I use them but I do like to wash a finished quilt. The quilt with the snake fabric border is finished (binding as well) so into the washing machine with six of these Colour Catcher sheets.
They have done their job picking up any dye in the water. I can't see any colour emigration so good job colour catcher.
It's a lovely autumn day, great drying weather. I really like the look of a quilt once it's been washed.
