Hello and welcome!
It really is a matter of practice practice practice until you find the technique(s) that works for you -- as well as the size of project, the types of fabric and batting and all the other variables.
Some people do wonderful things on tiny little old machines, I'm not one of them. Some people quilt in strips and do wonderful things, again, I'm not one of them. I got by on my old trusty machine with simple grids and curves but I was unable to do the designs I wanted to do.
I had access to a friend's long arm for a number of years and I got spoiled. For me, it is a natural thing to move myself and the head of the machine and not the quilt. Even with a deep-throated machine I still don't like moving the quilt around but I'm willing to put together my twin and smaller projects on my modern Bernina -- unfortunately my preferred design size is closer to queen.
I'm piling up completed tops waiting for quilting at a pretty steady and alarming rate.
