Tapestry wool?

What is tapestry wool exactly?
Anybody knows that?
I haven't heard it before. I googled it but I couldn't hit exact meaning of the word.

It occurred to me that I once bought a yarn which was for weaving and I was informed that most people weave tapestry and rug with that yarn here when I bought some of them for my husband's vest. It was almost two years ago.

That's it!
That kind of yarn is really tapestry wool, isn't it? Then I went to a store and asked for the tapestry wool. I seemed to surprised shop assistants at the store. They said they usually use stronger thread such as one that made of polyester or cotton for knitting garments but at the time I insisted that I really needed. I finally decided to buy one. They helped me so much to fit the yarn to my jacket color. They picked up the yarn skillfully. It was totally my jacket's color!

TUNA YARN

One on the left hand side is TUNAYARN which I think it to be tapestry wool.
The yarn is called filtgarn, means blanket or rug yarn/wool.

Is there something worng on the yarn I bought?

I hope not...
