I am a relatively new quilter; thus, my knowledge is somewhat limited -- I really don't know what I'm supposed, or not supposed to be able to do. My first pieced block quilt (a log cabin) was quilted on my Singer 201-2 (an old vintage machine in tip-top shape!). I rolled my quilt (half of it) and began my stitching in the center of the quilt. My quilt was a very large Queen Size, and yes, it was not easy, but I quilted it SITD, and had no puckers at all. Now, I'm not saying this quilt was perfect -- it wasn't, but I think it turned out pretty good for a "first"! I'll have to resize the photo and re-post later.
