I also found lame tape.
You can make your own bias-tape
I personally use the needle pin down method for making smaller tape.
The wide stuff that is double sided i to it manually by ironing it in half then ironing it inwards. So for 2" wide tap i cut 4" wide strips and hold in a 1/2" on both sides.
For PVC or Metallic Spandex Fabric instead of ironing directly you want a piece of fabric to iron over the PVC that has been folded so that you only steaming the PVC with heat.
Also in the case of spandex you won't need to cut it on a bias as it's already has a lot of stretch in the fabric.
