There are so many variables ! If I am just meandering I can get a queen quilt done in a few hours, it takes me about 30-45 minutes to load my quilt backing (I pin) batting and baste down the top. Then from there meandering is quick. Using the robotics is another story, it depends on the design. I just finished a lap quilt 60 x 80 that had 6 rows and each row took about 25 minutes to stitch out, yes I makes notes of how long it takes a row to stitch out so I can time doing other things in between. Find a place that rents longarm time and go check it out, you will usually have to pay to take the class to learn the basics before they allow you to use it.
