I also put pins no farther than hand-width apart and I have a large area of support (around & level with my machine bed) so there is no pulling from the weight of the quilt. Nor do I roll the quilt ... I bunch up and can then easily shove/pull/move??? quilt portions wherever they need to go. I have no room at this time for a long arm/frame; I have machine quilted several very large quilts. I try to always do SID first, then examine the quilt thoroughly front & back before I do more intricate stitching in the individual blocks or pieces. Important for me is to not overdo at one time; I don't allow myself to get tired; better to take many days to complete a quilt than to do myself an injury.
