I was under the impression that there are 2 kinds of Weaver's cloth. One is for clothing which is a firmer weight for things like slacks and jackets.
Then there is another kind, designed to be used for crafts, such as the needle punch. If you are making a pillow, it would be a firm background for the yarn that is used. There is some even firmer that will allow you to make a "throw" for your chair or sofa. Then an even heavier that can be used for throw rugs.
Ask at your fabric store about the different weights and what would best suit the project you might plan to make. There are kits availble which you might check into just to get more idea about this craft.
