Help with legion tailoring? Stuck at 90

I’m leveling legion tailoring and I’m almost done but I need the imbued silkweave cinch pattern and everything online tells me Leyweaver Erenyi in Val’sharah has it. She only has thread and other things like that. Maybe there’s something I’m misunderstanding. Is this something that becomes available after a quest line? I’m pretty sure I’ve finished my profession quest line here (I think). I just came back after being gone for almost a year. Does anyone know why this is? Or even have another suggestion to get to level 100 in legion tailoring? (I’m currently at 90). I even purchased the rank 2 and 3 of this pattern so I’m bummed I can’t find rank 1.

Have you got the Imbued Silkweave Bracers yet? If not then you haven’t completed all of the tailoring quests yet. The vendor only sells the new patterns once you’ve completed all of the quests.

There’s a list of all the quests in the comments on Leyweaver Erenyi on wowhead. https://www.wowhead.com/npc=93974/leyweaver-erenyi#comments

It appears I do not. Thank you
