Welcome aboard. I'm new here too. Seems to be lots of helpful people at all skill levels. I've been quilting about 40 years but only been long arming for the last 5 or so. The set-up I use belongs to a friend, although her table allows for pantograms she doesn't have the back arms for the machine and no computer driven designs -- but still a vast improvement over trying to stuff entire quilts through my little old sewing machine
For me the hardest part of the process is coming up with the quilting designs. I think in 2-D just fine but still working on 3-D!
