Thanks for your help! My friend has the SweetSixteen, I think the rails are about 15’. It’s all one continuous stitching, she does not have to stop to do any adjustments. I am impressed with it. My goal is to be able to stand while stitching and not have to do all the pinning by hand and struggling with the quilt. I have a Janome Horizon and I find it a pain getting my quilts thru the throat. So as a beginner I want to place my quilts on those three rollers and stitch away. I want the setup for my own enjoyment and not as a business. I have so many quilts, large runners and mats that I just want to quilt myself. Always drawing, even doing my own embroidery designs, I think I will adjust pretty easy to the stitching required, I will look at the Millie, and others, to gain insight. Not easy being a newbie wanting a starting point! Thanks, again, I appreciate input! Sandi
