I am quite new to Balenciaga handbags, so I don't have experience with the old leathers, only the new ones. Obviously I must like them, or I would not have purchased the handbags that I have. I think it adds uniqueness to the handbags and that no two Balenciagas will look the same. I like that. My Cornflower Twiggy is not as "veiny" as my Rouille Twiggy. The Cornflower I chose to be less veiny, the Rouille was fresh from the back stock room and what they had. I like it though, I like how in the 'veins' the colour is different, it adds dimension.
I wish you well,
Bridget
