I used it on some twin bed quilts I made my nieces. I found it to be not the greatest, especially trying to stuff it all under my machine to quilt. It was "sticky" and just not something I wanted to use again. I found I not only had to iron it to my quilt top but also my backing fabric. Double the work... :P
I think smaller projects that don't require alot of handling, it might be a better choice. I prefer hand basting.
HTH,
