Use of Wool thread in rug
 

I just made a chanille rug with cotton flannel. I just grabbed a good color of thread. I completely finished it (commenting to myself that the thread was very strange). Upon completion I realized I had used Aurifil Wool Thread. I am horrified. Does this mean I cannot wash, and in particular, I cannot put this rug in the dryer? I am amazed on how thick and heavy the rug is (5 layers of flannel plus one of cotton batting). I plan to use it by the bathtub. I also worry about mold, if it cannot dry quickly enough.

Are there any instructions on the packaging?

Sheep get wet, and hardly ever shrink.

Many wools can be washed - gently with little or no agitation - and line dried. Knitted wool sweaters had to be blocked back to shape after washing and then dried flat. Also, avoid temperature extremes of water. Tepid (lukewarm) to cool water for both the wash and rinses.

Depending on where you live, drying time may be an issue. Living in AZ, you forget how humidity changes things. We go home to VA for family reunion, towels never do get dry between showers.

My first thought was sturdiness. I’ve got some aurifil wool thread I use for my applique and it breaks really easy. Maybe tug on what you have to see how easily it breaks. Is it possible to “go over” your project with some cotton or poly thread to reinforce it?
