Your wondering if being able to promote an article of clothing that includes spider silk will have a higher retail price point than a standard cotton hoodie? That is the vexing question of the day?
Have you followed along on any of the handful of garments released by others claiming to have anything remotely related to some percentage of spider silk properties and the retail prices asked for said items?
This has to be a joke. After 12 years, and all of the decades prior spent by others to achieve mass produced spider silk, your query is "what's the big deal"?
