I use Thermolam Plus and it is a permanent bond. I have a press, so I can do large areas at one time. I place the fleece on the press with the fusible side up, place the fabric, wrong side down on top of the fleece and cover with a press cloth. I spray moisten the press cloth and then press for about 15 seconds. I have been doing this for years and it does stay adhered to the fabric. Sometimes I FMQ, sometimes I stitch in cross hatching and sometimes I just leave it as it is. I make a lot of purses and use it for them.
