Thank you for your replies - I've watched videos time and again - and I thought I was doing it correctly, but I haven't pressed the fold line. And now, I think I use my square up rulers to make sure it is placed accurately on the die. I've marked around the blades, but think I will also take a ruler and draw a line from one side to the other to get the fabric lined up correctly. I've done the selvage test to make sure the fabric is hanging correctly - and maybe I'm not getting that right. It is really frustrating.
