We have no control over what the factory in the Philippines calls Medium Stiffening. It varies from roll to roll and can not be returned or exchanged because the stiffening is lighter or heavier than last time you purchased it. If you absolutely need the stiffening to be the same each time buy the white or black UNSTIFFENED sinamay and stiffen it yourself. If you need colors, dye it first and then stiffen it. So sorry, this is as perfect as the world of sinamay gets, but since it is one of our best sellers, I think it is pretty darn perfect even without perfection.
Note: Colors will vary depending on your monitor and there will also be some variations due to dye lots.
