We used the tape with our Stairville stage curtains to make a 1m valance from the stage to the floor. The curtains came with velcro already attached and this roll of fastening tape fleece was the complementary side. It was sold for this purpose.
Initially the product worked well. However, over a weeks or so the weight of the curtain dragged on the tape and it started to come loose at the edges and had to be replaced in places.
Luckily we had plenty on the roll so this was not a problem, but I would recommend purchase of plenty of tape, as it is not reusable.
