I haven't used them, that is point, it's from examples of standard or commercial clothes that are old and well used that show the wrinkling or dimpling
And you base your opinion of fusible interfacings on old used clothing and not on personal opinion of using the product? I wouldn't call that experience something on which you could base an opinion of fusible interfacings. My observations and opinions are based on years of using the product and working in the home sewing industry. And no one has ever complained that my garments are of low quality.
