Kinda excited to see what cool fabrics N&F will have in store for us in the future. I don't know if this is even possible but it would be neat to see a horizontal indigo Warp thread and a vertical white Weft thread. I also would love to see a rapid-fade denim that speeds the whole fading process up 5x. Last NF dream denim for me would be a black on indigo overdye but the black has a leathery look to it. I think Nudie did something like that a few years ago but I never saw any faded examples.
I really want to see the thermo-colour changing denim previewed a few months ago in person. That fabric looked insane. Man, the NF guys must have such an awesome time doing their job.
