Crafting Furniture

I’ve been wanting to actually craft furniture for the New Mansion however there’s one material I cannot seem to gather no matter what I do, and there isn’t any guides I can really find for it.

I know it says you can get Damask in roam or errands but I have not gotten any errands with it as a prize and roam doesn’t really detail what you get besides xp and coin.

Is there a way I should be going about this or am I just having bad luck?
