I thought I understood but I guess I don't. I went to the altar with mats all ready for 14 pieces of shadowcloth to make my frozenshadoweave robe. I get there I click "create all" and it creates two pieces then engages the cooldown. Is that correct? They only allow you to make 2 pieces of shadowcloth every 4 days?
It depends on which tailoring you have. If you have shadoweave tailoring you can make 2 shadow cloth every 4 days, and 1 of mooncloth, and spellcloth every 4 days.
So yeah you can only make 2 every 4 days, thats why they are so expensive to buy.
