The Fine D'Aubusson tapestry wool is from Au Ver a Soie in France. It is a thinner thread similar to Crewel wool rather than a thicker tapestry wool.
* I order directly from the Au Ver A Soie in Paris and have access to their entire product line including Kits. I order once a month and will be building my in stock selection over the next year.
