I'm fairly new to FMQ and here's what helps me:
A large table so the quilt doesn't hang off
A snow carpet to make the surface slick. I cut a hole for the needle plate and tape it to the machine
Machingers gloves
They have helped me a lot. I also bought a Juki with a wider throat.
I've always been a hand quilter but wanted to learn to quilt by machine. Lots of practice is helping me too.
