You think, only vintage hat bodies are balky? Chance would be a fine thing! In this case, I had a surprise with a new, high-quality and expensive velour-capeline. After dry-spell I noticed, something had gone wrong. There were those furtive folds again on the back of the brim. That ment: Straining, damping, ironing…..At least for nothing. The folds laughed themselfes half to death about my efforts – and remained. But there is one thing, I can mention to my defense: The capeline was uncommonly stiff in some areas and not on the same gauge everywhere. Maybe that´s an explanation.
Well, I wear the hat anyway and the art nouveau-decoration is a good red herring. (So the eye of a beholder will not pause on the folds, but on the big colorful ribbon-roses! And that´s the way it should be!)
So don´t worry, if something goes wrong with your own millinery projects. Things happen usually and perfection is a state, that can only be reached seldom (or never!)
