I also prefer to use wss on red work designs. Also use it on sheer fabrics like tea towels where tear away would be too heavy and remaining cut-away would be visible on the front.
I use vilene too. If I think the stitches may get lost in the weave of the fabric, I put a sheet of vilene for a topper too. It keeps the stitches on top of the fabric.
I have inherited masses of old bed sheets. They make wonderful stabilisers!
Tear away is usually too hard on the stitches in redwork. the fiber like wash away is safer. Just have to soak it to get it all out if you want it to be "soft" afterwards. You can always used 2 layers of it if you think it needs it. Good luck!
I made curtains using fibrous washaway stabilizer with an Urban Threads thistle design and they came out looking wonderful.
