If you Google Curve Master a lot of things will pop up. Then look for You Tube. Or type in You Tube Curve Master into your search engine. That ought to help you find demos. I'll try to find the one I watched and post it. My husband installed the foot and adapter on my machine. I tend to hurry and try to force things. The one I bought had all the adapters, so I can use it on my Pfaff and FW. It didn't seem to make a big difference in price and I like that I can use it both machines. Try this address
