Can't craft Wu's Fighting armors
 

I have tried to craft both Wu's fighting collar and sash and I have been told on both recipes that "You cannot combine these items in this container type!" when I used both my Large Sewing Kit and in the loom in East Freeport in the upstairs of Velith and Bardo Imported Goods. I have used 1 vial of viscous mana, 4 unstacked heady kiola, a gorget or belt pattern, and 1 silk swatch for the collar and 2 for the sash. Here are some relevent links I could find.

The only Wu's available to make right now are the gloves. Apparently on live they didn't come out until later, so the devs took the ability to make it out of the game. It was in Sunday's patch notes.

Try using a Loom.

Wu's (other than gauntlets) wasn't available until 6 months or so after velious release.
