I have a 301A and I use it for FMQ a lot!
Okay I read that you know how to lower your feed dogs and that's located under your long bed towards the outside corner not facing you. There's a metal part that screws ( that protrudes in that area) that screw is for lowering your feed dogs. Turn that screw all the way to the opposite direction until it will not give. With that action your feed dogs are now lowered. And use a Singer needle only, not a Schmetz because these little machines WaNt their particular needles. Use a good thread, I've been using the Connecting Threads and my machine loves it.
When you get ready to piece your blocks, do not forget to screw that piece back to it's original because then you will not be able to move a stitch.
I got my FMQ foot from SewClassics, the less cost efficient one is going to challenge you and give you headaches.
I hope this helps!
