I know, I am in the wrong group here, but who can help?

I have a hardwood floor in my den. I have a plastic chair mat with no
teeth on the bottom so it won't damage my floor. But, on top of the
wood floor, I have an area rug.

The chair mat slides all over the place because part of it sits on a
wood floor, and part of it sits on a rug.

I have tried double-back tape, but no luck.

Can anyone help?

Thanks.

Look at your local sewing / fabric store.

A non-slip backing you can cut to size.
