Mine just looks at me sadly and looks at my already large stash and shakes his head. I guess he doesn't understand that the 5 shelves of fabric I already have doesn't contain the right combinations.
Since I use most of my stash for charity sewing, he just says, "save the receipt"
But I don't want him to be bothered by what I spend so it tends to come into the house in the grocery totes-the fabric ones you can't see through.
