how/where does this attach to your machine? What about the feedings/bobbin covering?

I have an older Bernina set into a sewing table. I use four pieces of painter's tape to secure it to the machine and table. When I need to refill the bobbin, I loosen the top pieces of tape and lay the grid back towards the front. I know it's a little inconvenient, but the benefit of having this seam guide have been more than worth it.

Are there thorough directions with it?

Yes, they come with thorough and clear directions.

Does this have a key (that you cut out) for lining it up correctly?

You can cut this to help with lining up on your machine

Could someone explain to me how this works? I'm at a loss. Thank you.

I would glad to answer your questions. This is a piece of plastic that lays on the extension table of your sewing machine and you line the center line with the needle. Then the line on the right is 1 quarter inch from the needle .your fabric runs along that line ,or for sewing from corner to corner line the square from the needle and the other corner down the center line for a diagonal seam. It basically helps you sew straight. I hope this was helpful. If you have any other questions I'd be happy to help explain it the best i can.
