I don't believe you are currently craft this item.
It requires 50x ash and 2x yarn. So it needs 52 inventory slots.
However you cannot open a cupboard and use a loom at the same time. Even though you are visually sitting on the loom and can open a cupboard, it disables the 'using loom' state. So you're either getting the error 'Requires using a loom.' or 'You do not have all the ingredients.'
Stockpiles of ash and looms do not work either. This could be because ash doesn't have its own stockpile type, it uses the junk type so the recipe is unable to draw from it automatically.
